The program incorporates NASA satellite data into an desktop software program called RETScreen Expert. RETScreen , a clean energy management software program developed by the Canadian government in collaboration with several international partners, including NASA.
Most of the environmental parameters -- like temperature, humidity, and winds -- included in the RETScreen project is developed by NASA's Global Modeling and Assimilation Office (GMAO). Based at NASA Goddard Space Flight Center in Greenbelt, Md., its computer model and data assimilation techniques enhance NASA Earth observations from more than 20 NASA satellites and missions.
However, the key data parameter, solar irradiance, provides a long-term record of daily averaged solar variability up to within about a week of real time. This solar variability replicates ground-based measurements very well and can be used to do things like monitor solar photovoltaic panel performance and place solar panels for optimal exposure to sunlight.
Wind resources are also incorporated into the POWER models and have important uses for energy efficiency analysis, such as helping to better calculate heat losses from buildings.

"Nitrogen dioxide (NO2) emissions, a major air pollutant, are closely linked to factory output and vehicles operating on the road. As both industry and transport come to a halt during this pandemic, NO2 emissions can be a good indicator of global economic activity -- and the changes are visible from space. These images from the Centre for Research on Energy and Clean Air (CREA), as well as satellite footage from NASA and the European Space Agency (ESA), show a drastic decline in NO₂ emissions over recent months, particularly across Italy and China."

The attached Space-based Quantification of per capita CO2 Emissions from Cities report provides the first independent estimates of direct per capita CO2 emissions (E pc) from space-borne atmospheric CO2 measurements from the Orbiting Carbon Observatory-2 (OCO-2) for a total 20 cities across multiple continents. The analysis accounts for the influence of meteorology on the satellite observations with an atmospheric model. The resultant upwind source region sampled by the satellite serves as an objective urban extent for aggregating emissions and population densities.
The study suggests that E pc declines as population densities increase, albeit the decrease in E pc is partially limited by the positive correlation between E pc and per capita gross domestic product.

"During the past five years, ethanol has been the fastest-growing agricultural export. As more nations adopt policies for lower-emission vehicle fuels, domestically produced ethanol can provide an immediate solution for their goals. We assert that there is little justification for EPA to maintain such an outdated calculation that otherwise could be easily corrected with existing, available analysis -- and straightforwardly address an unnecessary obstacle to international trade," the Senators wrote.
"Peer-reviewed science conducted by the USDA has affirmed that U.S. ethanol lowers greenhouse gas (GHG) emissions 39-43 pct versus gasoline. EPA has rejected all calls to update these calculations, instead using nearly 10-year-old data, which ignores the technological advancements in ethanol production", the Senators said.
The Senators called for the EPA to adopt the scientific model Greenhouse Gas & Regulated Emissions & Energy Use in Transportation (GREET) developed by the DOE Argonne National Laboratory, after studying 100 fuel production pathways and 85 vehicle systems to measure the life-cycle carbon emissions of vehicle fuels. More than 30,000 organizations worldwide use the updated GREET model, including the FAA, NASA, Ford and GM, BP and others. EPA does not use the updated model. (Source: Office of Sen.

"Global warming is prominent throughout the North. Ergo, climate news doesn't get much worse (well, actually, it could, and will) than the collapse of permafrost in the Canadian High Arctic's extreme coldest region (where): 'Observed maximum thaw depths at our sites are already exceeding those projected to occur by 2090. The aforementioned study, from 2003-2016, found permafrost melt up to 240 pct more than previous years. In geological terms, that's like winning the Indy 500, hands down. That permafrost had been frozen solid for 'thousands of years.' Accordingly, scientists predicted the permafrost 'wouldn't melt for another 70 years.' Yet, the landscape has already collapsed by up to three feet.
"Bottom line, the top 25 pct of the Northern Hemisphere, where permafrost is ubiquitous, is coming apart at the seams, and climate scientists are behind the eight ball while America's politicians deny the legitimacy of science and openly spit on the underlying thesis of anthropogenic global warming. In point of fact, Farquharson's '70-yr too early permafrost collapse' makes the onset of RGW look like a dead-ringer, but when?
"There's no getting around the fact that ecosystems are collapsing. The evidence is too palpable to ignore. It's serious; it's deadly, and it could be too late to do much to stop it, other than a last-ditch WWII Marshall Plan Worldwide Consortium dedicated to converting the world to renewable energy, and forcing removal of CO2 from the atmosphere, yet, those solutions take years and years of planning, setup, construction, and billions upon billions of funding. It's not happening.
Meanwhile, carbon that has been trapped in and under permafrost over eons readies to escape to turbo-charge an already over-saturated turbo-charged climate. It's literally happening right now. The waiting room is already full. Farquharson's study proves it, and Alaska's permafrost carbon emissions that compete with U.S. commercial CO2 emissions prove it, as sled dogs wade through it."

Forests can store large amounts of carbon and so monitoring photosynthesis is an accurate way to track global carbon levels and measure how much CO2 is being stored. For evergreen trees which remain green all year round, it’s challenging to measure photosynthesis and carbon uptake. In the new study, published in the journal Proceedings of the National Academy of Sciences, researchers found a way to use solar-induced fluorescence (SIF) emitted by evergreen trees to monitor seasonal changes in photosynthesis and GPP. SIF occurs when chlorophyll levels return from a dormant state, and a photon is emitted which produces a faint “glow” not visible to the naked eye. Satellites can now detect SIF glow, and the researchers used scanning spectrometers to measure SIF in an evergreen forest in Colorado. The team found that fluorescence was a reliable indicator of seasonal chlorophyll changes matching the same patterns found in deciduous forests. Having a way to monitor GPP in both evergreen and deciduous forests will help researchers understand how climate change is impacting forests over a large scale.
“Ultimately, measuring the small fluorescent glow from plants will allow us to see exactly timing and magnitude of carbon uptake from the terrestrial biosphere. This will help us understand how forests are responding to climate change and suggest how they might respond to future climate change,” said Troy Magney, research scientist of the NASA Jet Propulsion Laboratory and a lead author of the study.

The OCO-3 is designed to accurately measure the altering carbon cycle on Earth and how it will affect all its living inhabitants. The OCO-3 measurements can reduce the uncertainty of the natural fluxes of the global carbon budget, mainly due to anthropogenic emissions. The instrument can make nearly precise measurements at different times of the day due to its position in space. Scientists also aim to know how CO2 concentrations change throughout the day in various areas of the Earth.
The OCO-3's high-resolution spectrometers can also detect solar-induced fluorescence, a type of radiation emitted by plants. Plants only produce SIF during photosynthesis season, which is also the only time they absorb CO2.
The OCO-3 cost less than $100 million to construct and was developed by the NASA Jet Propulsion Lab (JPL)in California.
The OCO-3 is expected to launch prior to April 25 and is expected to continue for three years. (Source: JPL NASA, Tech Times, April 2019) Contact: NASA, (818) 354-4321, www.jpl.nasa.gov, www.nasa.gov

"By using a specially developed Fischer-Tropsch synthesis catalyst and advanced process engineering techniques, Renovare Fuels' technology can efficiently turn biogas into middle distillate fuel. The feedstock is sourced locally to the site and classified as a waste product, so the production cycle is objectively carbon neutral," according to the company.
The abundance of waste products means that the production of the biodiesel promises a low-cost sustainable alternative to fossil fuels. Renovare Fuels believes that the fuel could be priced at under 50 UK pence per litre in a quantity that could reshape the energy sector.
Renovare Fuels' technology, which was developed at the University of South Florida in conjunction with NASA and the US DOE, was proved successful in converting biogas into usable diesel during a trial at a US landfill in 2017, according to the company.

This was a significant indication that showed how gases not only CO2 but such as CFCs that deplete the ozone layer could have ramifications for climate. This finding was also at the core of future negotiations for the Montreal Protocol on Substances that deplete the ozone layer that followed in 1987. The Montreal Protocol benefits both the ozone layer and the climate system. Its effectiveness is much greater than the first phase of the Kyoto Protocol.

According to the study, premature deaths would drop in cities on every inhabited continent with the greatest gains in saved lives occurring in Asia and Africa. Kolkata and Delhi, India, lead the list of cities benefitting from accelerated emissions cuts with up to 4.4 million projected saved lives and up to 4 million projected saved lives, respectively. Thirteen other Asian or African cities could each avoid more than 1 million premature deaths and around 80 additional cities could each avoid at least 100,000 deaths.
The new projections underscore the shortcomings of taking the lowest-cost approach to emissions reductions, which permits emissions of carbon dioxide and associated air pollutants to remain higher in the short-term in hopes they can be offset by negative emissions in the far distant future, said Drew Shindell, Nicholas Professor of Earth Sciences at Duke's Nicholas School of the Environment.
"The lowest-cost approach only looks at how much it will cost to transform the energy sector. It ignores the human cost of more than 150 million lost lives, or the fact that slashing emissions in the near term will reduce long-term climate risk and avoid the need to rely on future carbon dioxide removal. That's a very risky strategy, like buying something on credit and assuming you'll someday have a big enough income to pay it all back," Shindell said.

In each test, a DLR Airbus A320 was fueled with a different blend of kerosene and Camelina-based biofuel. NASA's DC-8 flying laboratory followed a few kilometres behind an measured the pollutants in the Airbus' exhaust plume. Among the instruments on the flying laboratory were the ERc Instrument for Chemical composition of Aerosols (ERICA), from the Max Planck Institute and JGU Mainz.
NASA and DLR have been researching whether aviation biofuels are more eco-friendly for some time. According to a statement from the University of Mainz, previous studies have shown that 50 pct and 70 pct less soot particles form from a 50 pct biofuel mixture with 50 pct normal kerosene.
"At altitudes of eight kilometres, soot particles and water vapour form ice crystals at -50 degrees C, which can be seen in the sky as contrails. Among other things, the ice crystals prevent heat from escaping the atmosphere into space, meaning that every contrail creates its own small greenhouse effect."

The study bolsters a growing consensus that tropical forests are drying out or being cleared, burned and logged so fast that they now emit more carbon than they sequester. Whereas earlier estimates based on measurements of atmospheric carbon flows suggested that tropical forests might be carbon neutral or even a net sink, more-recent studies -- including ones based on data from NASA's Orbiting Carbon Observatory-2 satellite -- agree broadly with this recent paper, according to David Schimel, an ecologist at the NASA Jet Propulsion Laboratory (JPL) in Pasadena, California. Schimel suspects that human activities such as starting fires and natural factors including droughts have severly hindered tropical forests' carbon storage capability.
The study estimates that the world's tropical forests release approximately 425 million tpy of carbon -- equivalent to roughly 5 pct of the globe's annual fossil-fuel emissions and about five times more than estimated in 2011.
