1km-aggregated, RGB – Bands 1,2,1

Data Production & Archiving/Distribution• IIS MODIS system acquire about 2-3 day-scenes & 2-3 nightscenes, resulting in 4-5 GB of raw data per day - Raw data inpacket format with filenames of the form: YYYYMMDDHHMM• The system then produces Level 1b earth-view data products(6-8 GB/day) - archiving at komagome server including––––

Calibrated, Geolocated Radiance (1000 m) – all 36 bands – (*.1000m.hdf)
Calibrated, Geolocated Radiance (500 m) – 7 reflected bands – (*.500m.hdf)
Calibrated, Geolocated Radiance (250 m) – band 1 & 2 – (*.250m.hdf)
MODIS geolocation file (*.geo.hdf)• Quicklook images for each pass are produced and accessible on
MODIS web - http://yasulab.iis.u-tokyo.ac.jp/• Data distribution: free (through INTERNET)IIS MODIS System

Similar to the US MODIS DBnetwork (GSFC, USF, UW, OSU)
• Data sharing between sites in
the region for join study of
extreme weather events at
continental scale – dust storms,
typhoons, …
• Generate selected agreed
portions of data / products.
• Algorithm/products intercomparisons.
• Compositing process togenerate Asian mosaic (NDVI,LST/SST) in shortest time lag.
