- title :
- ABI L2 Total Precipitable Water
- summary :
- The Total Precipitable Water product consists of the water depth if it were condensed in the atmospheric column between approximately 300 hPa and the surface. The product is generated using a regression retrieval followed by an iterative physical retrieval that makes use of a radiative transfer model. Product data is generated both day and night.

- title :
- ABI L2 Total Precipitable Water
- summary :
- The Total Precipitable Water product consists of the water depth if it were condensed in the atmospheric column between approximately 300 hPa and the surface. The product is generated using a regression retrieval followed by an iterative physical retrieval that makes use of a radiative transfer model. Product data is generated both day and night.
