Data Product Information
The data processing center will produce nine Level 1B and Level 2B Standard Data Products:
| 1B-CPR | Level 1B Received echo powers |
| 2B-GEOPROF | Cloud mask and radar reflectivities |
| 2B-CLDCLASS | Cloud Classification |
| 2B-CWC-RO | Radar-only liquid/ice water content |
| 2B-TAU | Cloud optical depth |
| 2B-CWC-RVOD | Radar + visible optical depth liquid/ice water content |
| 2B-FLXHR | Radiative fluxes and heating rates |
| 2B-GEOPROF-Lidar | CloudSat CPR + CALIPSO Lidar Cloud mask |
Use the following resources to learn about and obtain CloudSat data:
| 1 | Download the CloudSat Data Products Handbook. It has general information on the CloudSat mission and the individual data products.* |
| 2 | Follow the Product Documentation link for more detailed online and hardcopy information about each product version. |
| 3 | Check the Data Issues page to see if there are any known issues or problems with product version you are interested in. |
| 4 | Review the Configuration Control page to see what the most recent versions are or to find out about data you have. |
| 5 | View the Release Status page to see if data have been processed for your days of interest. |
| 6 | Search for and order data from the Data Ordering System. |
File Naming Convention
| YYYYDDDHHMMSS = | Year, Julian day, hour, minute, second of the first data contained in the file (UTC) |
| NNNNN = | Granule number |
| CS = | Literal "CS" indicating the CloudSat mission |
| 2B-TAU = | Product name |
| GRANULE = | Indicates the data subset ("GRANULE" if the data are not subset) |
| S = | Data Set identifier ("P" for production release) |
| RVV = | Release number |
| EVV = | Epoch number |
| .hdf = | HDF-EOS file suffix |
Example:
CloudSat data products are made available in HDF-EOS format and are created with HDF-EOS 2.5 based on HDF 4.1r2. Later versions of the HDF and HDF-EOS libraries should be able to manipulate the files as long as they are in the HDF 4 series. Files delivered through the online ordering system are compressed (.zip).
Note: Publications or presentations that use CloudSat data must acknowledge the NASA CloudSat project. Please also inform the project of any such publications by submitting the full reference at Submit a Publication Reference.
