		:summary = "The Satellite Ocean Heat Content (OHC) Suite system produces two OHC files in ASCII and NetCDF where the output is defined on a 0.25 degree grid. For the daily files, the fields are: latitude, longitude, sea surface temperature (SST) in degrees Celsius, sea surface height anomaly (SSHA) in centimeters, mapping error, depths of 20degC (D20) and 26degC (D26) isotherms, ocean mixed layer depth (MLD), all in meters, and a satellite derived ocean heat content (OHC) in kJ/cm2. It runs once daily. OHC is mapped at 0.25 degree resolution with an accuracy within 10 to 15% of in situ data and a latency of 36 hours due to the receipt/processing required for the Sea Surface Height Anomaly data. Five GIF images were also to be created each day for OHC, SST, 20 degree isotherm, 26 degree isotherm, and Mixed Layer Depth. " ;
