MODIS Satellite Images available for FTP now from Tokyo University

Vietnam MODIS Satellite Images from Yasuoka and Takeuchi Lab, The University of Tokyo Prof Takeuchi from Institute of Industrial Science, University of Tokyo has provided the Daily Level 2 MODIS satellite on the following FTP site ftp://webmodis.iis.u-tokyo.ac.jp/UNU/ Naming rule is as follows: MXDYYYYMMDDhhmm-VAR-GEO MXD: MOD->Terra, MYD->Aqua YYYY: year MM: month DD: day hh: hour in UTC mm: minute VAR: variables (chlor_a, sst, nLW_551 and K_490) GEO: geographical location All data are packed in 16bit signed inter (INT16) in little endian. Following scaling factor (a) is used to get original value (y) from pixel value (x) on each parameter respevtively. y = a * x Chloroplyll-a: 0.0001 SST: 0.005 (Celcius degrees) normalized water leaving radiance at 551nm: 0.001 diffuse attenuation coefficient at 490nm: 0.0002 If you are using Seadas or ENVI to display the Vietnam MODIS image, it will be input as flat file. Some detail information is needed to read the file. Following are the ex...

News! 071109 AN ERA OF EARTH OBSERVATIONS: LOOKING BACK AT 50 YEARS

AN ERA OF EARTH OBSERVATIONS: LOOKING BACK AT 50 YEARS Source: http://earthobservatory.nasa.gov/Newsroom/MediaAlerts/2007/2007110925922.html Since the launch of Sputnik I in 1957, thousands of satellites have been sent into space on missions to collect data about the Earth. Today, the ability to forecast weather, climate, and natural hazards depends critically on these satellite-based observations. Satellites have revolutionized how humans view and understand the home planet, helped address fundamental scientific questions, and enabled a plethora of applications with important societal benefits. Continued Earth observations from space will be required to address scientific and societal challenges of the future.Where will a developing hurricane make landfall? What is the status of the ozone layer? How much will sea level rise? No other single measurement platform has revolutionized the ability to address these and other fundamental Earth science questions as much as satellites orbiting ...

SeaWiFS - A Decade of Ocean Color

A Decade of Ocean Color NASA Earth Observatory New Images http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=17801 It may seem obvious that life is distributed across Earth in uneven patches: lush forests teem with life, while barren deserts support a relatively small number of specialized plants and animals. But scientists have only started to glimpse the pattern of life in Earth’s oceans with the advent of Earth-orbiting satellites, and the greatest contribution has come from a small satellite called the Sea-viewing Wide Field-of-View Sensor (SeaWiFS). Designed to orbit the Earth for five years collecting information about the oceans, SeaWiFS entered its eleventh year of operation in September 2007. Along with its predecessor, the Coastal Zone Color Scanner, the satellite provided scientists their first view of how plants are distributed across the globe’s oceans and revealed that, like land, the oceans contain rainforest-like areas where plants proliferate and d...
