Land Remote Sensing Program
The USGS is fostering the use of land remote sensing technology to meet local, national, and global challenges.
The William T. Pecora Award is presented annually to individuals or groups that have made outstanding contributions toward understanding the Earth by means of remote sensing. Nominations are accepted for public and private sector individuals, teams, organizations, and professional societies. Both national and international nominations are welcome.
It has been a full year since the launch of the Landsat 8 satellite! During this time, over 160,000 Landsat 8 images have been acquired and made available to users worldwide. Landsat 8 is the latest success in a decades-long NASA and U.S. Geological Survey partnership that has provided a continuous record of change across Earth's land surfaces since 1972.
The USGS is committed to continually improving the data coming from its latest satellite, Landsat 8. Since its launch in February 2013, the project's engineers have been refining the data as they learn more about the performance of the satellite. On February 3, 2014, the Landsat 8 archive will be cleared from the online cache and reprocessed to take advantage of calibration improvements identified during its first year of operation. All Landsat 8 scenes will be removed from the online cache at this time and these data will then be reprocessed starting with the most recent acquisitions and proceeding back to the beginning of the mission. Reprocessing is expected to take approximately 50 days. Most users will not need to reorder data currently in their local archive; however, users are encouraged to review all Landsat 8 calibration notices and evaluate the improvements as they relate to specific applications.
AmericaView, a university-led, state-based consortium designed to promote remote sensing science and technology, was awarded a nearly $1 million National Land Remote Sensing Education Outreach and Research Activity grant by the U.S. Geological Survey this week through a competitive process. AmericaView will use the increased funding to further develop the national consortium; expand the science of remote sensing through education; and promote awareness of remote sensing technology for providing crucial insight into such issues as environmental climate monitoring, natural resource management, land cover mapping, projected land use change, and disaster analysis.
The Department of the Interior's U.S. Geological Survey (USGS) and NASA presented the 2013 William T. Pecora Award for achievement in Earth remote sensing to Dudley B. Chelton, distinguished professor of Earth, Ocean, and Atmospheric Sciences at Oregon State University, Corvallis. Chelton was recognized for his contributions to ocean remote-sensing science, education, and applications.

The Department of the Interior has released its remote sensing activities report. This report, from the DOI Remote Sensing Working Group, provides a sampling of the many FY12 applications of remote sensing across the Department. Remotely sensed data, information, and resources contribute significantly to mission-critical work across the DOI. Spanning data sources from aerial photography, to moderate resolution satellite data, to highly specialized imaging sensors and platforms, DOI personnel use remotely sensing capabilities to evaluate and monitor land-surface conditions over the vast areas for which DOI has responsibility.
What is the coldest place on Earth? It is a high ridge in Antarctica on the East Antarctic Plateau where temperatures in several hollows can dip below minus 133.6 degrees Fahrenheit (minus 92 degrees Celsius) on a clear winter night.
With remote sensing satellites, including Landsat 8, researchers have recorded new measurements of the Earth's coldest temperatures. The satellite imagery not only allows scientists to take the temperature of these inhospitable locations, but enables them to figure out what sort of weather brings on the record-breaking cold.
The quest to find out just how cold it can get on Earth -- and why -- started when NASA researchers were studying large snow dunes, sculpted and polished by the wind, on the East Antarctic Plateau. When the scientists looked closer, they noticed cracks in the snow surface between the dunes, possibly created when wintertime temperatures got so low the top snow layer shrunk. This led scientists to wonder what the temperature range was, and prompted them to hunt for the coldest places using data from satellite sensors : MODIS (Moderate Resolution Imaging Spectroradiometer), AVHRR (Advanced Very High Resolution Radiometer), and Landsat 8 - TRS (Thermal Infrared Sensor).
