As part of NASA approach and methodology they have used Earth Observation Systems and Applications for Public Health and Air Quality Models to provide a method for bridging gaps of environmental, spatial, and temporal data for tracking disease. This presentation will provide an overview of projects ...
Aqua is one of the three satellites composing NASA's Earth Observation System. Aqua was launched on May 4, 2002. Aqua orbits such that it crosses the Equator in the afternoon (approximately 1:30 p.m. local time) complementing Terra, which crosses the Equator in midmorning. The afternoon eq...
Fig. 4. Overview of Earth Observation from space (individual images modified from: NASA/JPL-Caltech/ESA/Copernicus). Active and passive sensors are two main types of remote sensing instruments utilized in spaceborne Earth Observation (Fig. 4). Active instruments such as radars, lidars, laser and...

"This pilot program is an innovative and efficient way for us to acquire, examine and evaluate a wide range of private-sector Earth-observation data," Michael Freilich, director of NASA's Earth Science Division, saidin a statement at the time. "As our very capable NASA research satellite fle...
Planet collaborates with ESA to advance Greek satellite services Los Angeles CA (SPX) Mar 25, 2025 Planet Labs PBC (NYSE: PL), a key player in delivering daily Earth observation data, has entered a new agreement with the European Space Agency (ESA) to support Greece's National SmallSat Pr...
to use free and lower-resolution data from weather satellites, NASA added. But Landsat's competitive advantage evaporated in 1986 when a French satellite launched with similar capabilities to the U.S. series. (The satellite was called SPOT, a French acronym for "System for Earth Observation.")...
全球长期微波植被光学深度气候档案(VODCA) 植被光学深度(VOD)描述了植物对辐射的衰减情况。VOD是频率以及植被含水量的函数,并延伸到生物量。VOD在生物圈研究中有许多可能的应用,如生物量监测、干旱监测、物候学分析或火灾风险管理。我们合并了来自各种空间传感器(SSM/I、TMI、AMSR-E、AMSR2、WindSat)的VOD观测数据,以...
