GPM Core Spacecraft Beauty Passes

1. How has our view of Earth changed since the first “Earth Rise” image from the 1969 Apollo mission?2. Why is this global view important? 3. What’s next?4. How can our viewers celebrate Earth Day tomorrow?5. Where can we learn more? We think of NASA as a space agency, but NASA also has eyes on our planet. NASA and its science partners have a collection of Earth observing satellites, some that circle Earth every 90 minutes. NASA's view of Earth from space provides a perspective that can't be gained from the ground. Satellites circle the entire globe, seeing both where people live and the remote parts of deserts, mountains, and the vast oceans that are difficult, if not impossible, to visit. All of this data is important for helping us better understand our home planet. NASA Scientist Dr. Michelle Thaller is available on Friday, April 21 from 6:00a.m. – 9:00a.m. EST to chat with you on camera about new NASA science, and show your viewers some of the great Earth science research NASA is doing.

Complete transcript available. Not all raindrops are created equal. The size of falling raindrops depends on several factors, including where the cloud producing the drops is located on the globe and where the drops originate in the cloud. For the first time, scientists have three-dimensional snapshots of raindrops and snowflakes around the world from space, thanks to the joint NASA and Japan Aerospace Exploration Agency Global Precipitation Measurement (GPM) mission. With the new global data on raindrop and snowflake sizes this mission provides, scientists can improve rainfall estimates from satellite data and in numerical weather forecast models, helping us better understand and prepare for extreme weather events.

Complete transcript available. This is a conceptual animation showing how the size and distribution of raindrops varies within a storm. The animation travels from the top to the bottom of a storm. Blues and greens represent small raindrops that are 0.5-3mm in size. Yellows, oranges, and reds represent larger raindrops that are 4-6mm in size. A storm with a higher ratio of yellows, oranges, and reds will contain more water than a storm with a higher ratio of blues and greens. Credit: NASA's Goddard Space Flight Center/Conceptual Image Lab This is a high-resolution conceptual image showing the distribution of different sized raindrops within a storm. Blues and greens represent raindrops between 0.5-3 mm in size and yellows, oranges, and reds represent raindrops between 4-6mm in size.Credit: NASA's Goddard Space Flight Center/Conceptual Image Lab A GIF optimized for posting on Twitter.This shows the distribution of different sized raindrops within a storm. Blues and greens represent raindrops between 0.5-3 mm in size and yellows, oranges, and reds represent raindrops between 4-6mm in size.

NASA's GPM satellite is measuring the size and distribution of raindrops globally. A GIF optimized for posting on Twitter.With GPM’s three-dimensional snapshots of drop size distribution, scientists can gain insight into the structure of a storm and how it will behave. A GIF optimized for posting on Twitter.In the mid-latitudes, raindrops can originate from snowflakes, allowing them to melt into bigger raindrops compared to the tropics.

Video profiles of researchers and scientists in the field during the OLYMPEX field campaign (2015-2016).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 Olympic Mountain Experiment, or OLYMPEX.This is Rachael Kroodsma's profile on YouTube.This is Joe Zagrodnik's profile on YouTube.

B-roll of a Dual-frequency Dual-polarized Doppler Radar (D3R). The D3R is a fully polarimetric, scanning weather radar system operating at the nominal frequencies of 13.91 GHz and 35.56 GHz covering a maximum range of 30 km. The frequencies chosen allow close compatibility with the GPM Dual-frequency Precipitation Radar system, which was selected for flight on the GPM core spacecraft. This footage was captured during the NASA-led field campaign OLYMPEX. B-roll of the NASA NPOL radar is a research grade S-band, scanning dual-polarimetric radar. It is used to make accurate volumetric measurements of precipitation including rainfall rate, particle size distributions, water contents and precipitation type. This footage was captured during the NASA-led field campaign OLYMPEX. B-roll of scientists working on the ground instruments used to verify precipitation measurements from NASA's Global Precipitation Measurement (GPM) satellite.

Much of the study region is in Olympic National Park, where motorized vehicles are not permitted.

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 2014.This is a selection of b-roll that captures the scientists and instruments at work in Washington State.

An animation depicting the build-up of precipitation data on a flat map from the Global Precipitation Measurement constellation of satellites, resulting in the IMERG global precipitation data set.This video is also available on our YouTube channel. The colorbar for liquid precipitation (rain). The colorbar for frozen precipitation (snow). The ten currently-flying satellites in the Global Precipitation Measurement Constellation provide unprecedented information about the rain and snow across the entire Earth. This visualization shows 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 the constant rainfall patterns along the Equator to the storm fronts in the mid-latitudes. The dynamic nature of the precipitation is revealed as time speeds up and the satellite data swaths merge into a continuous visualization of changing rain and snowfall. Finally, the video fades into an visualization of IMERG, the newly available data set of global precipitation every thirty minutes that is derived from this satellite data.This is a newer version of the animation and uses a modified version of the Liquid Precipitation Rate colorbar. This newer colorbar improves the display of higher rain rates. Related pages
