PDD_SAP_L2-UTH_V1_R4.pdf (updated in November 2015)Version history:
Version 1.00: Released October 2013. Original versionVersion 1.01: Released May 2014. The BT-to-UTH retrieval is performed after correction of the limb effect on the BTs. For this correction, the measured BTs at a given incident angle are redefined at an equivalent nadir viewing geometry, from a look-up-table. In V1.00 a step of 5° in incidence angle was used, whereas in the current V1.01 a step of 2° has been preferred.
Version 2.00: Released January 2015. Added UTH uncertainty. Minor format corrections.
