Compute mean-variable field at a given date

It is very frequent nowadays that mean gravity fields include time-variable terms. This form allows you to compute the value of the CNES/GRGS mean fields at a given date, by summing the different variable terms:

Indicate the gravity model and day of interest

The format of the date must be one of the following:

  • Decimal years. Example: 2012 or 2009.50
  • Julian day 1950. Example: 21512
  • YYYYDOY. Example: 2011365
  • YYYYMMDD. Example: 20111231
