Washington: US space agency, NASA has released the most accurate and comprehensive collection of rain, snowfall and other types of precipitation data ever assembled to public.
This new resource for climate studies, weather forecasting, and other applications is based on observations by the Global Precipitation Measurement (GPM) Core Observatory, a joint mission of NASA and the Japan Aerospace Exploration Agency, with contributions from a constellation of international partner satellites, NASA said in a statement.
The GPM Core Observatory, launched from Japan on Feb 27, 2014, carries two advanced instruments to measure rainfall, snowfall, ice and other precipitation.
“We are very pleased to make all these data available to scientists and other users within six months of launch,” said Indian-born researcher Ramesh Kakar and GPM programme scientist in Earth Science Division at NASA headquarters in Washington DC.
Instruments on the GPM Core Observatory and partner satellites measure energy naturally emitted by liquid and frozen precipitation.
“With this GPM mission data, we can now see snow in a way we could not before,” added Gail Skofronick-Jackson, a project scientist at Goddard Space Flight Center in Maryland, adding that scientists and modellers can use the new GPM data for weather forecasts, estimating snow-pack accumulation for freshwater resources, flood and landslide prediction, or tracking hurricanes.
This revolutionary information also gives scientists a better grasp of how storms and precipitating systems form and evolve around the planet, providing climate modellers insight into how precipitation might change in a changing climate.
The instruments are designed not only to detect rain and snow in the clouds, but to measure the size and distribution of the rain particles and snowflakes.
