Washington:  An Indian-American scientist working with NASA has revealed how temperature and rainfall patterns may change through the year 2100 because of growing concentrations of greenhouse gases in the Earth’s atmosphere.

New high-resolution global climate data prepared by Ramakrishna Nemani, project scientist at the NASA Earth Exchange (NEX), a big-data research platform in California, can be viewed on a daily timescale at the scale of individual cities and towns.

It will help the scientists and planners in conducting climate risk assessments to understand local and global effects of hazards, such as severe drought, floods, heat waves, and losses in agriculture productivity better.

“This is a fundamental dataset for climate research and assessment with a wide range of applications,” Nemani said in a statement.

“NASA continues to produce valuable community-based data products on the NEX platform to promote scientific collaboration, knowledge sharing, and research and development,” Nemani added.

The data shows projected changes worldwide at a regional level, in response to different scenarios of increasing carbon dioxide simulated by 21 climate models.

“With this new global data-set, people around the world have a valuable new tool to use in planning how to cope with a warming planet,” noted Ellen Stofan, NASA chief scientist.

This NASA data-set integrates actual measurements from around the world with data from climate simulations.

These climate simulations used the best physical models of the climate system available, to provide forecasts of what the global climate might look like under different greenhouse gas emissions scenarios.

The NASA climate projections provide a detailed view of future temperature and precipitation patterns around the world at a 25-km resolution, covering the time period from 1950 to 2100.

The 11-terabyte data-set provides daily estimates of maximum and minimum temperatures and precipitation over the entire globe. (IANS)

Emmy Awards 2018: NASA Nominated for Stunning Footage of Cassini voyage to Saturn

The Emmy Awards nominations have turned out to be more diverse than last year

The Academy of Television Arts and Sciences (ATAS) has nominated NASA’s Jet Propulsion Laboratory (JPL) for Outstanding Original Interactive Program for its coverage of the Cassini mission’s Grand Finale at Saturn.

The Primetime Emmys will be awarded by the ATAS in Los Angeles on September 17.

The Creative Arts Emmys, which include interactive awards, will be presented during a separate ceremony on September 15 at the Microsoft Theatre in Los Angeles, NASA said in a statement on Friday.

In 2017, after nearly 20 years in space and 13 years revealing the wonders of Saturn, NASA’s Cassini orbiter was running out of fuel. As a final act, Cassini began a whole new mission — its Grand Finale, where it journeyed into the unknown and ended with a spectacular plunge into the planet.

Cassini’s first, daring dive into the unexplored space between the giant planet and its rings kicked off the campaign on April 26 in 2017.

It culminated on September 15, 2017, with live coverage of Cassini’s plunge into Saturn’s atmosphere, with the spacecraft sending back science to the very last second.

JPL created a multi-month digital campaign to celebrate the mission’s science and engineering accomplishments and communicate why the spacecraft must meet its end in the skies of Saturn.

The multi-faceted campaign included regular updates on Twitter, Facebook, Snapchat, Instagram and the Cassini mission website, multiple live social, web and TV broadcasts during which reporter and public questions were answered.

A dramatic short film to communicate the mission’s story and preview its endgame; multiple 360-degree videos, including NASA’s first 360-degree livestream of a mission event from inside JPL mission control.

The Emmy Awards nominations have turned out to be more diverse than last year. Fantasy drama “Game of Thrones” has earned 22 nominations for the coveted Awards, while HBO’s 17-year streak as the most nominated network has been broken by Netflix. (IANS)
