RCMRD installs MODIS satellite data receiving station

Representatives of RCMRD during the launch of the MODIS receiving station

RCMRD, the Regional Centre for Mapping of Resources for Development, and host of UN-SPIDER's Regional Support Office in Kenya, recently installed and launched a new satellite receiving station. The station is capable of receiving data from Moderate Resolution Imaging Spectro-radiometer (MODIS) sensor on the US American Aqua and Terra satellites, as well as other Earth Observation satellites.

NASA satellites track Hurricane Arthur from Space

Hurricane Arthur captured by NASA on 4 July.

Several satellites kept track and monitored Hurricane Arthur from the initial phases to the development of a Hurricane and to a post-tropical storm.

On 29 June 2014, a low-pressure area in the center east of Florida developed. That area evolved afterward into Tropical Depression 1, captured on June 30 by the MODIS instrument aboard NASA's Aqua satellite.

Alaska: Satellites show land surface temperature anomalies

Temperature anomalies in Alaska in January 2014

NASA's Terra satellite captured from Space land surface temperature anomalies for Alaska in the last week of January. Between 23 and 30 January 2014, Alaska has seen record-breaking warmth.

The data compiled by the MODIS sensor on Terra was processed into a map showing the differences in temperature between the 2014 temperatures and the 2001–2010 average for the same week. Areas with warmer than average temperatures are shown in red.

Satellite images show the Great Lakes in Canada covered with ice

NASA's satellite Aqua captured this MODIS natural color image of lake Erie
MODIS infrared image of Lake Erie in Canada showing the ice cover

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite acquired these images on January 9, 2014. The extreme cold weather that paralyzed North America early this year brought thick ice over the Great Lakes in Canada.

The top image shows Lake Erie in natural color, the second one shows a blend of shortwave infrared, near infrared and red that help distinguish ice from water. Ice is pale blue, the thicker the brighter, open water is navy, and snow is green.

NASA maps global temperature anomalies in US and Europe

MODIS image caught by NASA's Terra satellite shows the polar vortex over America
MODIS image caught by NASA's Terra satellite shows high temperatures in Europe

NASA satellite data shows the recent weather divergences on Earth - particularly in North America and Europe. At the beginning of 2014 the temperatures in the northern hemisphere showed how the atmosphere can produce two contrasting weather extremes at the same time. While in northern America the temperatures fell way below zero, most of Europe enjoyed temperatures of +10 degrees Celsius.

NASA sees thick smog layer over China

Smog covers Eastern China

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured an image of the haze spreading from Beijing to Shanghai on 7 December 2013. The expansion of the smog to the south of China is not that common as for the northeast.

Remote Sensing helps locate the Coldest Spot on Earth

Remote Sensing image showsing the coldest place on Earth

NASA's Landsat 8 satellite defined the coldest place on Earth - 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.

Scientists from NASA evaluated 21 years’ worth of data, including the most detailed global surface temperature maps, developed with data from remote sensing satellites. They found that the temperatures were record low many times between Dome Argus and Dome Fuji, but the new record was set on 10 August 2010.

Using space technology to monitor flooding in Thailand

Severe flooding affected large stretches of Thailand’s Chao Phraya River

The South Asia region is especially prone to flooding. Annually, flooding takes hundred of lives and causes damages in tens of billions US dollars.

In a collaboration of NASA’s Jet Propulsion Laboratory and the Hydro and Agro Informatics Institute of Thailand, sensorweb technologies are being used to enhance monitoring of flooding especially in Thailand. This technique is used for detection, early warning and analysis of high resolution imagery.

Colorado Floods: NASA Satellite sees Inundations from Space

Colorado on 13 September 2013

NASA's Aqua satellite was able to acquire imagery of the Colorado floods on 14 September 2013 during a break in precipitation with its Moderate Resolution Imaging Spectroradiometer (MODIS). Intense rainfall in northern and eastern Colorado had led to widespread floods caused by as much as 46 centimeters of rain between 9 to 15 September 2013.

NASA's Aqua satellite shows wildfires in central Russia

 Intense heat wave in central Russia

On July 25, 2013 the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite captured valuable images from the Khanty-Mansiyskiy and Yamal-Nenetskiy districts of Russia, showing the smoke billowing from large fires that have been affecting this region during the month of July.
