-------- Original Message -------- Subject: Various current satelite layers on remote sensing Date: Thu, 25 Feb 2010 02:50:31 -0800 (PST) From: MARZIO VENEMAN <[log in to unmask]> To: Angie Cope <[log in to unmask]> Dear subscribers Maps-Listserv., With reference to the above, I take pleasure informing you as follows. Please note that the Earth Observatory has various social internet connections, e.g. RSS, Ezine and on all network platforms as mentioned with this email sign-off. http://earthobservatory.nasa.gov/IOTD/view.php?id=42805&src=fb <http://earthobservatory.nasa.gov/IOTD/view.php?id=42805&src=fb> On February 24, 2000, after two months of post-launch testing, sensors on NASA’s Terra satellite began opening their shutters and making their first observations. Stunning pictures are only part of Terra’s story, however. The small globes show just a few of the Earth’s “vital signs” that Terra’s five sensors monitor. In all five globes, gray indicates no data. * *Biosphere.* MODIS tracks photosynthesis by measuring growing vegetation on land and chlorophyll from phytoplankton in the ocean. Dark green on land (June 2009) and light colors in the ocean (March 2009) show the most productive areas. * *Carbon Monoxide.* Released by burning plants and fossil fuels, long-lived carbon monoxide (CO) is commonly used to trace the path of pollution as it spread from its source. The Measurements of Pollution in the Troposphere (MOPITT) <http://www.atmosp.physics.utoronto.ca/MOPITT/home.html> sensor collected these measurements in June 2009. The highest concentrations of carbon monoxide are dark orange. * *Aerosols.* Particles like pollution or dust—aerosols—affect both air quality and climate. Between March and May 2007, the Multi-angle Imaging Spectroradiometer (MISR) <http://www-misr.jpl.nasa.gov/> measured high aerosol concentrations (purple) from Saharan dust over the Atlantic Ocean and smoke and pollution over the Americas. * *Elevation.* With its stereo imagers, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), <http://asterweb.jpl.nasa.gov/> can take an image of the same ground area from two different angles. This stereo view allowed scientists to generate the most extensive satellite-based topographic model of the Earth to date. * *Net Radiation. *The balance between solar energy entering and thermal (heat) energy leaving Earth is the net radiation. This balance determines our planet’s average temperature. These observations from the Clouds and the Earth’s Radiant Energy System (CERES) <http://science.larc.nasa.gov/ceres/index.html> sensor show net radiation in March 2009. Orange shows energy surpluses (more energy in than out), while green shows energy deficits (more going out than coming in). I trust this information is sufficient for your purposes, in case you require any additional details, please do not hesitate to contact the undersigned.
