Important notice for the temporary observation stop of TANSO-FTS-2 for the GOSAT-2 maneuver operation (May 10 - Early June, 2024)
We would like to inform you that the GOSAT-2 maneuver operation is scheduled for the following period:
May 10 - early June, 2024 (UT)
All FTS-2 observation will be cancelled during the period. CAI-2 observation will be also suspended temporarily. Normal GOSAT-2 observation will re-start from early June.
Thank you for your understanding for this issue. We will inform users again when we know more details.
Note on the Level 1 product for GOSAT TANSO-FTS TIR users
There is a possibility that the GOSAT L1B TIR spectrum product may contain data with high temperature radiance values at a frequency of approximately 0.02%. To confirm the presence of such high temperature regions, one can examine the radiance temperature within the window region of 900cm^-1±10cm^-1, where temperatures in the range of several thousand Kelvin can be observed. It is recommended to avoid using products that exhibit such occurrences.
Due to system maintenance, web updates will stop on the following dates.
2024/02/22 10:00JST(01:00UTC) - 2024/02/26 10:00JST(01:00UTC)
Please also note that access will not be available on February 26, 2024 from 10:00(01:00UTC)to 15:00JST(06:00UTC).
