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	Dowload the CloudSat Data Products Handbook. It has general information about 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).
