Sounder Cloud Top Pressure (GOES) Cloud top pressure is derived from the GOES Sounder radiance information. The images are color enhanced to show the variation of height and type of clouds over a region.

Total Precipitable Water (SSM/I) Also referred to as Water Vapor, this product shows the total atmospheric moisture over oceans. The water vapor is derived from the passive microwave sensor SSM/I, which has 7 channels of 19 GHz (H, V), 22 GHz (V), 37 GHz (H, V), and 85 GHz (H, V), where H is the horizontal polarization, V is the vertical polarization. The water vapor varies from 0 to 80 with accuracy of 0.1 kg/m^2. The product is updated once per day at 4 am EST.

This product is generated initially by the Fleet Numerical Meteorology and Oceanography Center (FNMOC). NOAA/NESDIS gets the product through an interagency program referred to as the Shared Processing Program in which NOAA, the US Air Force and US Navy participate. OSPO converts the product into HDF-EOS and WMO BUFR formats and distributed to users.

Low Cloud Base Regional Imagery The Low Cloud Base (LCB) products are generated from the GOES Imager and help to identify ceilings less than 1000 feet for aviation users. These products display possible Instrument Flight Rule (IFR) ceilings as red, and non-IFR ceilings as green. Some areas of IFR ceilings may not be detectable by the GOES product due to insufficient cloud depth, obscuration by cirrus, or insufficient temperature data. Conversely, some areas denoted as IFR by the GOES product may have higher cloud bases in areas of multiple inversions. Cloud heights (ft) observed at surface stations are overplotted in black.
