In early 2017 ECMWF prepared L2B and L2C datasets for testing by the Aeolus CAL/VAL teams (based on L2Bp v2.30). These were prepared by running a realistic simulation of 16 orbits of Aeolus using ECMWF model data (wind, temperature, pressure, cloud properties) as input to the Aeolus simulator (E2S) for the date 1/10/2015. The CAL/VAL rehearsal datasets (generated in 2017) are provided here:
- The Level-2B datasets (in Earth Explorer format) are here: ALD_U_N_2B.tar.gz
- Example of Aeolus L2B BUFR products are here: extracted_BUFR.tar.gz
- The Level-2C datasets (in Earth Explorer format) are here: ALD_U_N_2C_reprocessed.tar.gz
Updated datasets:
The data has been regenerated (in March 2018) with the most recent processing chain: E2S v4.01, L1B v7.01 and L2B v3.00.
Earth Explorer files (normally distributed by ESA (https://aeolus-ds.eo.esa.int/oads/access/)):
- The input Level-1B Earth Explorer data (only first 3 files due to their large size): ALD_U_N_1B_first_3_files.tar.gz
- The auxiliary data used by the L2B processor (not including AUX_MET_12, since too large): L2Bp_inputs_without_AUX_MET.tar.gz
- The Level-2B Earth Explorer data: ALD_U_N_2B_first_half.tar.gz and ALD_U_N_2B_second_half.tar.gz
- The Level-2B report files: ALD_REP_2B.tar.gz
L2B BUFR data produced by ECMWF (to be distributed via EUMETSAT during the mission):
- The Level-2B BUFR data (one file per orbit): ALD_B_N_2B.tar.gz
- The extracted L2B BUFR (6 hourly chunks, as part of ECMWF pre-processing): extracted_BUFR.tar.gz
- Known issues in the BUFR (that will be resolved in the next delivery v3.10):
- Sat ID should be 48 rather than 600
- Missing values in some azimuth, elevation angle and los spacecraft velocity
- Missing HLOS winds not set to invalid results
- dHLOS_dp values are too big by a factor 100 (wrong units). Also noted that dHLOS_dp and dHLOS_dT need more precision.
