PROGRAM sanity_check_LIM3 ! Checks if a LIM3 restart is physically consistent and outputs the updated ! version. Strongly based on limupdate.F90, and on sanity_check_LIM2 ! (c) Original from Chris König Beatty ! (c) Re-written by Francois Massonnet, November 2012, ! (c) Refreshed for NEMO3.6, Francois Massonnet, April 2016 ! francois.massonnet@uclouvain.be ! ! ! TODO: create subroutines to automaticate the extraction of NetCDF! ! ************************************************************************************************** ! PLAN of the program ! ! ! 0. Header ! 1. Check existence of NetCDF files, grab command line args ! 1) Ice analysis file ! 2) Ice forecast file ! 3) Oce analysis file ! 4) Oce forecast file ! 5) Mask file ! 6) Mesh file ! 2. Get dimensions, nb ice categories, nb ice/snow layers, allocate, get ice thickness bounds ! 3. Load ice+oce and mask+mesh variables from files ! 4. Ice analysis sanity check ! 1) Regularize ice concentration and adapt other variables ! accordingly ! 2) Manually update the snow and ice heat content according to volume ! changes ! 3) Rebin categories with thickness out of bounds (CALL itd_reb() ) ! Note that itd_reb() calls shift_ice if a shift needs be done ! 4) Several ice corrections ! For example, set volume to zero where concentration is zero. ! 5) Shrink ice (CALL shrink_ice() ) ! If sum(a_i) > 1 or < 0 or some a_i > 1 or < 0, then ice is shrunk ! or reset to zero. ! 6) Rebin categories with thickness out of bounds (CALL itd_reb() ) ! We do it once again as thickness may have changed ! during processes 2) and 3) ! 7) Final concentration check (CALL conc_check() ) ! The program stops if > 1 or < 0 occurs in sum or individual categories ! This can ultimately cause trouble in the code as a term (1-sum(a_i))^0.6 ! occurs in a routine => negative power 0.6 is very baaaad ! If ice concentration is just above 1 or just below zero (numerics) then ! the program resets to zero or one. ! 5. Oce analysis sanity check ! 1) Compute the difference between forecast and analyzed sea salinity ! If larger than XXX PSU, bound variations by that value ! Also update the sea surface salinity variable accordingly ! 2) Same for sea temperature; replace analysed temperature by forecast if ! less than -2°C ! 3) Limit ocean velocities to [-2,2] m/s ! 6. Record the files. The original file is copied and the variables are dumped ! in it ! 1) Ice analysis file ! 2) Oce analysis file !*************************************************************************************************** ! ! 0.
