History of DMSP-OLS Data Availability







1965 - DMSP begins
1972 - Existance of DMSP declassified. Film archive initiated.
1992 - Digital DMSP archive initiated at NOAA-NGDC. The U.S. Air Force requires
NGDC to hold OLS data for 72 hours prior to release. Data retrieval from archive based
on 8mm tape reproduction and airmail
September 28, 1999 - DMSP-OLS data delivered to MAFFIN via APAN.
October 5, 1999 - DMSP-OLS data delivery to MAFFIN and CRISP (Singapore)
becomes operational
December 21, 1999 - The U.S. Air Force relaxes 72 hour hold to 3 hours.
January 22, 2000 - NGDC delivers 3 hour old DMSP-OLS data to MAFFIN.
February 11, 2000 - Delivery of 3 hour old DMSP-OLS data to MAFFIN and
CRISP becomes operational.

Necessary Conditions for Agricultural Monitoring
Using Satellite Data
(Disaster Warning, Statistics, and Management)
1. Short interval data (1 - 3 weeks)
2. Semi-real time data (2 -72 hours)
3. Long term data (2 – 50 years) and database
4. Wide area data
5. Low cost of satellite data

What’s the Tsukuba WAN ?
Tsukuba WAN is the network for research collaboration and
cooperation among industries, universities and governments.
Its ultrahigh-speed access ring network is linking many
institutes in Tsukuba area.
This is intended to improve usability of recourses possessed by research
institutes in Tsukuba, such as supercomputer, large-scale database, and
computer simulation software.
The network construction was begun in 2000, and operation was started at
May 2002. The Tsukuba WAN symposium was held on May 2, 2002 with the
opening ceremony.
At the symposium, some research program and results of usage of Tsukuba
WAN, were introduced and their concept were discussed.
