Development of a Radiometric Correction Algorithm for OCTS Data
3.Experiments
The LAC and GAC data of OCTS level 1A data were processed developed algorithm. After processing results were compared from LAC of OCTS level 1B and BGAC of level 2. Naturally, the result of GAC must be compared from level 1B, because there is no level 1B of GAC product.
Conclusions
From the results, the striping noises are gone out and the result were not so different from level 1B product distributed by NASDA.
We noticed from temperature of black body were not stable. Therefore, we must develop new algorithm considered unstable temperature for high accuracy correction.
Finally, the PaNDA committee will distribute the software package via internet. The next address described PaNDA software in detail.
