Joe Zagrodnik is a student at the University of Washington who is working with NASA scientists to measure the properties of rain and snow in the Olympic National Park.

From November 10 through December 21, NASA and university scientists are taking to the field to study wet winter weather near Seattle, Washington. With weather radars, weather balloons, specialized ground instruments, and NASA's DC-8 flying laboratory, the science team will be verifying rain and snowfall observations made by the Global Precipitation Measurement (GPM) satellite mission on a NASA-led field campaign, The...

Rachael Kroodsma is the instrument scientist for the CoSMIR on board NASA's DC-8 airborne laboratory as part of the OLYMPEX field campaign.

The Olympic Mountain Experiment, or OLYMPEX, is a NASA-led field campaign, which will take place on the Olympic Peninsula of Washington State from November 2015 through February 2016. The goal of the campaign is to collect detailed atmospheric measurements that will be used to evaluate how well rain-observing satellites measure rainfall and snowfall from space. In particular, OLYMPEX will be assessing satellite measurements made by the Global Precipitation Measurement (GPM) mission Core Observatory, a joint mission by NASA and the Japan Aerospace Exploration Agency (JAXA), which launched in...

NASA scientist Dalia Kirschbaum explains how the Global Precipitation Measurement Mission's Core observatory has an instrument that can see layer by layer through a storm.

In this visualization of data by NASAs Goddard's Space Flight Center, we see Hurricane Joaquin when it was a tropical storm. Red and green colors show rain and the ice and snow at the top of the storm is visualized here in blue.

Understanding hurricane structure helps weather forecasters around the world determine a storm's structure and where it may be going.

The Global Precipitation Measurement (GPM) mission core satellite provided many views of Tropical Cyclone over its very long life. GPM is a satellite co-managed by NASA and the Japan Aerospace Exploration Agency that has the ability to analyze rainfall and cloud heights. GPM was able to provide data on Kilo over its 21 day life-span.

Landslides are among the most common and dramatic natural hazards, reshaping landscapes -- and anything in their path. Tracking when and where landslides occur worldwide has historically been difficult, because of the lack of a centralized database across all nations. But NASA researchers have updated the first publicly available Global Landslide Catalog, based on media reports and online databases that bring together many sources of information on landslides that have occurred since 2007. The catalog, originally released in 2010, is still the only one of its kind.

Around 6000 landslides are...

In 1997 when the Tropical Rainfall Measuring Mission, or TRMM, was launched, its mission was scheduled to last just a few years. Now, 17 years later, the TRMM mission has come to an end. NASA and the Japan Aerospace Exploration Agency (JAXA) stopped TRMM’s science operations and data collection on April 8 after the spacecraft depleted its fuel reserves.

Animation of precipitation rates over the Amazon Rain Forest as it pulsates with the diurnal cycle. Notice how during the day precipitation amounts increase and then decrease nightly. The ten satellites in the Global Precipitation Measurement Constellation provide unprecedented information about the rain and snow across the entire Earth. These visualizations show the constellation in action, taking precipitation measurements underneath the satellite orbits. As time progresses and the Earth's surface is covered with measurements, the structure of the Earth's preciptation becomes clearer, from...

Rain, snow, hail, ice, and every slushy mix in between make up the precipitation that touches everyone on our planet. But not all places rain equally. Precipitation falls differently in different parts of the world, as you see in NASA's new video that captures every shower, every snow storm and every hurricane from August 4 to August 14, 2014. The GPM Core Observatory, co-led by NASA and the Japan Aerospace Exploration Agency (JAXA), was launched on Feb 27...
