AATSR processing uses the following instrument-specific ADFs: • Browse Product Lookup Data (ATS_BRW_AX) • L1B Characterisation Data (ATS_CH1_AX) • Cloud Lookup Table Data (ATS_CL1_AX) • General Calibration Data (ATS_GC1_AX) • AATSR Instrument Data (ATS_INS_AX) • Visible Calibration Coefficients Data (ATS_VC1_AX) • L1B Processing Configuration Data (ATS_PC1_AX) • L2 Processing Configuration Data (ATS_PC2_AX) • SST Retrieval Coefficients Data (ATS_SST_AX) • LST Land Surface Temperature Coefficients Data (ATS_LST_AX) Note that because the PC1 file contains the orbit period, two versions were maintained following the execution of the mission extension orbit manoeuvres in October 2010 (Envisat 2010+). AATSR processing also uses the following generic Envisat ADFs: • Land/Sea Mask Data (AUX_LSM_AX) • Digital Elevation Data (AUX_DEM_AX) • Orbit State Vector Data (various, see below) Several datasets were available for use as the Orbit State Vector (OSV) data, with the DOR_VOR dataset being preferentially selected: • DORIS Precise Orbit State Vectors (Version D) (DOR_VOR) • Envisat Restituted Orbit State Vectors (AUX_FRO) • Envisat Predicted Orbit State Vectors (AUX_FPO) Table 1 presents the processor version and static auxiliary data files that were used in the AATSR reprocessing. ---------------------------------------------------------------------- Table 1.

In addition to the static files shown in Table 1, new dynamic auxiliary files were also used: • Visible Calibration VC1 files (ATS_VC1_AX): a complete dataset for the entire mission has been generated and was used; these are a new generation of VC1 files and contain the measured long-term drift correction. • Orbit State Vector OSV files (DOR_VOR and AUX_FRO): the reprocessing preferentially used the Version D DOR_VOR dataset, which is more complete and is of higher resolution than the operationally used AUX_FRO files.
