Specifies the data to be used in the plotting of a thermodynamic diagram from observations data. The icon field assist button provides a tailor made MARS request to help with the data specification. The data should be upper air sounding data (VSNS - Vertical Sounding Non-Satellite ). Please note that PILOT observations (winds only) do not have enough data for plotting a thermodynamic diagram.

Specifies the data to be used in the plotting of a thermodynamic diagram from model field data. The icon field assist button provides a tailor made MARS request to help with the data specification. The data should include gridded model fields of Temperature and Specific Humidity. These parameters must have the same number of levels and they will be used to compute the Dew Point parameter. Fieldsets U and V wind components are optional, but if given they will be used to compute the wind vectors data unit. These two components must have the same number of levels, but not necessarily have the same number of levels of Temperature and Specific Humidity. If the data is given in model levels then a Logarithm of Surface Pressure field must be provided too. The data can be provided as a single GRIB file or as multiple GRIB files.
