We’re taking you into a clean room at NASA’s Goddard Space Flight Center where the ICESat-2 satellite is currently being monitored. A small fraction of the light photons bounce off Earth’s surface and return to the instrument, where a photon-counting detector times their flight. Segmented into several minute granules.

This page provides comprehensive examples on how to access and visualize various NASA HDF/HDF-EOS files using Python (pyhdf/h5py), NCL, MATLAB ®, and IDL ®.Other tools and programming languages examples can be found here. Two JAXA datasets used in this animation are the 10-km daily sea ice concentration and the 10 km daily 89 GHz Brightness Temperature.This animation shows one of the major regions where this pumping occurs, the North Atlantic Ocean around Greenland, Iceland, and the North Sea. Sea ice thickness is typically estimated by first measuring sea ice freeboard - how much of the floating ice can be observed above sea level. • Donya Douglas-Bradshaw, Advanced Topographic Laser Altimeter System (ATLAS) instrument project manager at Goddard

Along-track atmospheric backscatter data, 25 times per second.
To help document this, ICESat-2's height change measurements will have a precision of less than an inch – ground-truthed, in part, with efforts like this Antarctic campaign. ICESat-2 will help scientists investigate why, and how much, our cryosphere is changing in a warming climate. In Photon Jump, a 3-minute short animation, a brave photon of light named Pho must travel from a NASA spacecraft down to Earth and back again to help complete a crucial science mission.

ICESat-2’s sole instrument, called the Advanced Topographic Laser Altimeter System (ATLAS), is being put to the test in this clean room and in a nearby thermal vacuum chamber, before engineers attach it to the rest of the ICESat-2 spacecraft.Downloadable high-resolution infographic illustrating the major technology and science objectives of the Ice, Cloud and land Elevation Satellite-2.These illustrations are an outcome of the ICESat-2/SCAD Collaborative Student Project.The Ice, Cloud and land Elevation Satellite-2, or ICESat-2, is a laser altimeter that will measure the heights of Earth’s surfaces. Seat Views. As part of the GLOBE Program, students and teachers from 121 countries can participate in the campaign, share their data around the world, and collaborate with students and teachers to design research projects based on the data collected within GLOBE and from the NASA ICESat-2 Mission.

A ground track shows ICESat-2's global coverage which repeats about once every 90 days. Surface height at specific length scale. Its Advanced Topographic Laser Altimeter System (ATLAS) measures height by timing how long it takes individual light photons to travel from the spacecraft to Earth and back.

Even small amounts of melt across areas as vast as Greenland or Antarctica can result in large amounts of meltwater contributing to sea level rise. Club. This article outlines how to order NSIDC DAAC data using advanced searching and filtering. There are also options for downloading via a command line or client.

NASA.gov brings you the latest images, videos and news from America's space agency. HDF is the prescribed format for standard data products that are derived from EOS missions. Height change maps for each ice sheet, for each mission year, and for the whole mission.

The heights of the ATM data are the 'true' heights.Arctic Daily Sea Ice Concentration from Arctic Minimum 2016 to Arctic Maximum 2017This animation shows the seasonal change in the extent of the Arctic sea ice between the Arctic minimum, September 10, 2016, and Arctic maximum on March 7, 2017.
