The MODIS black-body temperature data exist in raw DN form, in both the Level 1A file and the Level 1B OBC file. File specifications for these products may be found on the Level 1B Product Information and Status page.

Each file contains a Vdata named "Engineering BB data". There are 12 fields corresponding to the 12 BB thermistors. The field names are "TP_BB_TEMP01", ..., "TP_BB_TEMP12". The formulas implemented in Level 1B code to convert the telemetry DNs to temperatures in engineering units are from a memo written by Jack Xiong and Tim Dorman of MCST.

In addition to the raw DNs, the granule average BB temperature in Kelvin is reported in each of the four L1B products in the ECS core metadata as "AveragedBlackBodyTemperature", field "PARAMETERVALUE.1".
