Description

MODULE earthConstants_mod (prefix=’ec’ category=’8. Low-level utilities and constants’)

Purpose

Define public constants related to the Earth.

Prefixes:

  • ec_ (Earth constants), for miscellaneous values from diverse sources or

  • ec_wgs_ (World Geodetic Syatem) when they are explicitly from WGS84 specification.

Needed modules

  • mathphysconstants_mod: MODULE mathPhysConstants_mod (prefix=’mpc’ category=’8. Low-level utilities and constants’)

Variables

  • earthconstants_mod/ec_jyear [real,parameter]

    Standard (Julian) year

  • earthconstants_mod/ec_omega [real,parameter]

    Approximation, see for instance ec_wgs_Omega below.

  • earthconstants_mod/ec_r1sa [real,parameter]

    1.56955588945241177170D-07 ! Modified to explicitly 1/ec_ra

  • earthconstants_mod/ec_ra [real,parameter]

    ECMWF topographical mean radius (Authalic radius, eg ec_wgs_R2,+average topography)

  • earthconstants_mod/ec_rayt [real,parameter]

    Another topographical mean (NOAA)

  • earthconstants_mod/ec_rday [real,parameter]

    Standard day

  • earthconstants_mod/ec_rg [real,parameter]

    …616 ? This is Lambert IGF at 45 lat (g45). The WMO standard for conversions is …665.

  • earthconstants_mod/ec_romega [real,parameter]

    Angular rotation (approx., again)

  • earthconstants_mod/ec_sidday [real,parameter]
  • earthconstants_mod/ec_sidyear [real,parameter]

    Not really sidereal year, seems rather anomalistic year (odd).
