Abstract
This paper describes the inter-calibration approach and key results of Kalpana-1geostationary satellite. The normalized calibration technique is attempted in order to re-calibrate the Kalpana-1 Infrared ( 10.8 μm) channel and remove the effect of the temporal non-linearity of sensor response due to degradation of the sensor based on ISCCP (International satellite cloud climatology project) procedure over the Indian Ocean. The study region of the inter-calibration is ± 10° NS latitude of the equator; 64°-84° longitude east. INSAT-3D Infrared ( 10.8 μm) and Mid-infrared ( 3.8 μm) channel data were also used for inter-satellite calibration. The primary data used for Kalpana-1 and INSAT-3D inter-calibration is VHRR (Very High Resolution Radiometer) Infrared brightness temperatures and NOAA-19 AVHRR channel-2 and channel-4 brightness temperatures from May to December 2009 and February 2015. The reprocessing of Kalpana-1 products using NOAA coefficients have also applied to the old Kalpana-1 data. The results show the Kalpana-1 derived products are comparable to NOAA data. The major objective of this work is the generation of a Fundamental Climate Data Record ( FCDR) of calibrated and quality controlled INSAT geostationary sensor data for weather and climate prediction.
