Rainfall is essential for life across Earth’s landscapes. In addition to moving tremendous amounts of water through Earth’s atmosphere, rain clouds also move tremendous amounts of energy. When water evaporates from the surface and rises as vapor into the atmosphere, it carries heat from the sun-warmed surface with it. Later, when the water vapor condenses to form cloud droplets and rain, the heat is released into the atmosphere. This heating is a major part of Earth's energy budget and climate. These maps show monthly total rainfall amounts in millimeters from January 1998 to the present, derived using data from the Tropical Rainfall Measuring Mission (TRMM) satellite, which is a joint mission between NASA and the Japan Aerospace Exploration Agency. High rain totals are represented as blue shades, while little to no rainfall totals are shown in white. TRMM measures rainfall in the tropics. High-latitude regions, where TRMM does not record rainfall, are gray. The most obvious pattern in these total rainfall maps is seasonal change. A band of heavy rain moves north and south of the Equator seasonally. || ", "hits": 18 }, { "id": 10579, "url": "https://svs.gsfc.nasa.gov/10579/", "result_type": "Produced Video", "release_date": "2010-02-25T00:00:00-05:00", "title": "A Warming World Promo", "description": "This short video announces the launch of the \"A Warming World\" Web page on NASAs Global Climate Change Web site:http://climate.nasa.gov/warmingworld/A Warming World features videos, images, articles and interactive visuals that discuss rising global temperatures and the impact of greenhouse gases as the main contributor to modern climate trends.

This data set, shown on a globe, is derived from monthly data collected in 2004. The ocean color is derived from applying a depth shading to the bathymetry data. The Antarctica coverage snown is the Landsat Image Mosaic of Antarctica. Behind the Earth is a skymap from the Tycho and Hipparcos star catalogs. This skymap is plotted in plate carrée projection (Cylindrical-Equidistant) using celestial coordinates making them suitable for mapping onto spheres in many popular animation programs. The stars are plotted as gaussian point-spread functions (PSF) so the size and amplitude of the stars corresponds to their relative intensity. The stars are also elongated in Right Ascension (celestial longitude) based on declination (celestial latitude) so stars in the polar regions will still be round when projected on a sphere. Stars fainter than the threshold magnitude, usually selected as 5th magnitude, have their magnitude-intensity curve adjusted so they appear brighter than they really are. This makes the band of the Milky Way more visible. Stellar colors are assigned based on B and V magnitudes (B and V are stellar magnitudes measured through different filters). If Tycho B and V magnitudes are unavailable, Johnson B and V magnitudes are used instead. From these, an effective stellar temperature is derived using the algorithms described in Flower (ApJ 469, 355 1996). Corrections were noted from Siobahn Morgan (UNI). The effective temperature was then converted to CIE tristimulus X,Y,Z triples assuming a black-body emission distribution. The X,Y,Z values are then converted to red-green-blue color pixels. About 2.4 million stars are plotted, but many may be below the pixel intensity resolution. The three most conspicuously missing objects on these maps are the Andromeda galaxy (M31) and the two Magellanic Clouds. || ", "hits": 267 }, { "id": 3523, "url": "https://svs.gsfc.nasa.gov/3523/", "result_type": "Visualization", "release_date": "2008-01-07T00:00:00-05:00", "title": "Seasonal Landcover for Science On a Sphere", "description": "The Blue Marble Next Generation (BMNG) data set provides a monthly global cloud-free true-color picture of the Earth's land cover at a 500-meter spatial resolution.
