About JASMES SGLI Standard data (STD)

SGLI Standard data (JASMES format) are stored in netCDF4 files whish are generated by resampling the SGLI standard data in HDF5 files onto the JASMES-Grid.

Scheduled to update

・Global LTOA(8-day, monthly) data are reprocessing 2018-2021(Product:LV01-11, LS01-04, LT01-02, LI01-02, LGEI, LGEV, LGEP). We will announce after creation.For detail, please refer to here.(2022/12/5)
・Some incorrect values are stored in the xx_STD data set stored in the Global statistics products.We plan to reprocess and publish it. As soon as the reprocessing is completed, we will announce and the data will be replaced.(2022/12/5)

Data updates

2023/06/20 We released JASMES Global/Japan AROT products which are reprocessed for a bug of SGLI standards products.
By the reprocessing, snow contamination due to the bug is improved. For details of the reprocessing, please refer to here.
2023/03/16 ・Global CLFG(Daily) have been published on JASMES SGLI Standard monitor.
・Added the Polar Stereo (North/South) to the target area.
 Term : Daily, 8-day, monthly
2023/01/06 The climatological data/anomaly images of AROT and the JASMES aerosol statistical product have been published on JASMES SGLI Standard monitor.
For detail of the new product, please refer to here.
For details of the anomaly image, please refer to here. (2023/01/06)
2022/12/08 ・Japan Daily SICE data(2021/6-7) was reprocessed.
2022/12/05 ・All JASMES SGLI Standard products has been updated to ver.3.
・Statics products for Ocean around Japan(8-day,monthly) were released(SST、PAR、CHLA、TSM、CDOM). For detail, please refer to here.
・Anomaly Image were released(LST、NDVI、CHLA、SST、SWR、AROT).For detail, please refer to here.
AROT climatic anomaly images are under construction. We will announce after creation.


・The data from 2018 January to March is during the initial checkout period, so the observation operation and sensor settings are different from usual.
・The latutude and longitude of the netCDF data are stored in Float32. Please check Area and resolution when using.
・For 8-day and monthly, input data may be less when the minor version is switched.
・AROT(8-day,monthly) is different for global product and Polar Stereo product.
 Data to use when creating, Global:proprietary Aerosol statistical product of JASMES SGLI Standard product monitor, Polar Stereo:Standard Product.

Area and resolution

JASMES-Grid format is defined as the following (Global and Japan area same as JASMES MODIS data).
Areapixel sizeLatitude and Longitude (pixel center value)
Global 0.05deg Upper left Lon:0.0deg.E, Lat:90.0deg.N
Lower right Lon:359.95deg.E (-0.05deg.W), Lat:90.0deg.S
Japan 0.0025deg Upper left Lon:123.00125deg.E, Lat:49.99875deg.N
Lower right Lon:149.99875deg.E, Lat:24.00125deg.N

Polar Stereo (North/South) is as follows. Latitude and longitude information for each pixel is stored in netCDF.
