Providing data for the Common Database
The evaluation of passive imager cloud properties retrievals is part of the CREW. Hereto, a Common Database of cloud retrievals from different algorithms is build, which will be filled with retrievals of the different data providers. Below you will find relevant information for uploading your cloud retrievals to the common database. Note: the selected Golden Days are similar to those selected for CREW-2. Thus, providers that already have provided their data for CREW-2, and that do not want to update their datasets or add new ones, do not need to upload their datasets again.
DATASET SPECIFICATIONS
We have selected five Golden Days that are listed in Table 1. During several hours of the selected Golden Days the A-Train satellites aligned with AVHRR on-board NOAA-18. Our evaluation study will focus on these hours. However, we encourage the data providers to upload their datasets of the five Golden Days for the full 24 hrs. The study area is restricted to the SEVIRI full disk. The following data are desired for the Common Database:
- SEVIRI 15 minute data of the MSG disk preferably covering the full 24 hrs during the golden days (5x24hrs);
- MODIS swath data covering the MSG disk preferably covering the full 24 hrs during the golden days (5x24hrs);
- AVHRR swath data covering the MSG disk during the hours where NOAA-18 was aligned with the A-Train satellites
- Other instruments (MERIS/POLDER/..) preferably covering the full 24 hrs during the golden days (5x24hrs).
You can upload your data to the Common Database till 31 May 2011 through the FTP server at ICARE, which is assessable for CREW members after registration.
