A new NASA study about snowmelt in Wyoming shows, that the snow in a basin in northwest Wyoming now disappears about 16 days earlier than it did in the period from the 1970s through the 1990s. Snowmelt, as a water source, has a significant impact on agriculture and ecosystems in Wyoming.

New study suggests large organised storms cause rainfall increase

A new study, partly based on satellite data, finds the cause of increasing rainfall in the wettest regions of the tropics: more frequent large and well-organised thunderstorms.

The Australian Research Council Centre of Excellence for Climate System Science (ARCCSS) and NASA have developed a joint research project whose results are published online in "Nature". It reveals that rainfall increases seen in places such as the western Pacific in recent decades are due to large storms happening more frequently.

NASA's soil moisture mapper (SMAP) was launched on 31 January to map and detect global soil moisture. These maps will support the understanding of the interlinkages of Earth's water, energy and carbon cycles. The monitoring of SMAP will also promote weather and climate prediction as well as the monitoring of natural hazards.

NASA’s Global Precipitation Measurement mission has produced its first global map of rainfall and snowfall.

The GPM Core Observatory – launched one year ago on 27 February 2014, as a collaboration between NASA and the Japan Aerospace Exploration Agency – acts as the standard to unify precipitation measurements from a network of 12 satellites. The result is NASA's Integrated Multi-satellite Retrievals for GPM data product, called IMERG, which combines all of these data from 12 satellites into a single, seamless map.

NASA: Measuring atmospheric rivers from air and Space

NASA's ER-2 instrumented research aircraft is supporting CalWater 2015, a multiagency, interdisciplinary field campaign, designed to improve the understanding of when and how California ends up on the receiving end of atmospheric rivers. Atmospheric rivers are short-lived weather events that carry a flood of moisture from the tropics to the U.S. West Coast. The instrument also measures how much rain these events can bring, which is a crucial concern in the state’s ongoing historic drought.

US might face super-droughts in the future

The south-west of the United States could face severe droughts in the future, scientists found

Scientists of NASA's Goddard Institute for Space Studies, have found that the south-west and the central plains of the United States of America could face super-droughts in the future. 

The study published in the journal Science Advances compares earlier droughts with climate simulations for the coming decades. The team reconstructed past climate conditions and compared these with 17 climate models and soil moisture assessments.
