Reading the code

RTE and its related optics packages aspire to follow a set of coding conventions:

• Module names start with mo_, class/type names with ty_.
• Real variables are defined with working precision wp; logical variables with wl. Both Fortran KIND parameters are set in mo_rte_kind.F90
• Most procedures are functions which return a string. A non-empty string indicates an error of some kind.
• Procedures operate on multiple columns (profiles) at once. Problems are dimensioned by column, layer, and spectral quadrature point.
• Procedures are agnostic to vertical ordering
• Units are MKS
• Procedures (with the exception of testing code) do not perform I/O
