You need to apply
corrections for the infrared brightness
temperature derived from the IR channel data and calibration tables,
for the earliest period of GMS-5 observation (June 1995 to November 1996).

Download Instruction
We banned following naughty applications and users
- An SNS widget application which made abnormally high access to SE/00Latest.jpg. The application provider should establish his own cache server for this purpose and get the image only once an hour. Also, he should include proper credit to our site in his application.
- A user who made a utility program to get our archive data repeatedly. Such an application should keep its cache to store the data once retrieved.
- A user who requested a single 00Latest.jpg file every once in a ten seconds. Although the request was in conditional, 10sec is way too short. You should at least wait 5 min to check new data availability.
