JAXA Global Change Observation Mission-Climate (GCOM-C) called “SHIKISAI” has been started the global observation by Second-generation Global Imager (SGLI), which has 250-m spatial resolution with 1150-1400 km swath and nineteen multiple channels in 0.38-12 um wavelengths including two polarization channels.
GCOM-C/SGLI has observed various seasonal and year-to-year earth environment changes such as changes of aerosols accompanied with wildfires, snow cover, vegetation, land-surface and sea-surface temperature, chlorophyll-a concentration and so on. Because more than several tens of years observation are required to monitor the long-term change and study the climate change, we have started to make longer timeseries and anomaly map with 5-km resolution for global and 250-m resolution around Japan by synthesizing with MODIS and other satellite data. GCOM-C will continue the observation operation to produce longer own timeseries with effective use of the SGLI characteristics including polarimetry, near-UV, and 250-m resolution even after the five-year planned operation period util 23 December 2022.
