## GLI Sample Image

- GLI sample image over Japan is shown here. This image shows typical winter scene of Japan. Sea-ice and snow covered area is clearly observed. Cloud streak along to Japan sea causes heavy snow to middle to northern area of Japan.
- Based on these images, cloud/snow properties, vegetation index, sea surface temperature and ocean color are derived.

-     - Automated Triggered mode operation for sending Downlink Message,
-     - Interactive data collection,
- 2. Calculation of the location of NASDA Reference Beacons.
-     Calculate the location of the Beacons from Doppler shift data in DCS    level 0 data, by DCS processing software.
- 3. Evaluate the accuracy of the calculated location.
- 4. Joint Research using ARGOS next system with other parties (if possible).
- 5. Operation of NOAA ARGOS system in EOC, for delivering regional DCS     level0 data of NOAA satellites to CLS.

## Conclusions

**ADEOS-II Ground system Evaluation Result in ADEOS-II Initial Checkout phase**
- The basic functions of data acquisition, recording, L0 data generation and L0 data delivery at all the stations were confirmed.
- The basic function of MMO (operation planning for global data acquisition, registration of operation result information) were confirmed.
- The function of DCS L0 processing and data delivery were confirmed.
- EOC’s functions for the ARGOS Next system were confirmed.
- ADEOS-II Ground system meets the requirements from ARGOS Next system.
**Routine Operation**
- Routine operation of ADEOS-II and NOAA DCS data delivery is being done properly with no big issue.
- EOC keeps confirmation of functions and performance of DCS ground system.
