Description
Atmospheric n-dimensional fields
Interpolated to profile locations and used as both a priori and initial guess for retrieved parameters as well as specifying profiles of non-retrieved quantities (p, T, VMRs).

Notes
  1. These files are a way of supplying gridded climatological information (i.e. more than just a single profile as with the .atm files) which will be interpolated within MORSE to match the profile location and time.

  2. Although logically 2- or 3-dimensional arrays, within MORSE these are actually represented as pointer arrays, so no 'padding' is required to fill out these arrays to match the maximum dimension.
