Hi
Do you have access to the gitlab repository crocotools ? Commit 54d83443 from last may (12).
There are in this some commit for extracting forecast data, but if you need to extract analysis data, you should update in the same way : make_OGCM_mercator.m / download_mercator_python ....
Also in crocotools_param.m, just add :
motu_url_reana='http://nrt.cmems-du.eu/motu-web/Motu';
service_id_reana='GLOBAL_ANALYSISFORECAST_PHY_001_024-TDS';
product_id_reana={'cmems_mod_glo_phy_anfc_0.083deg_P1D-m' ...
'cmems_mod_glo_phy-cur_anfc_0.083deg_P1D-m', ...
'cmems_mod_glo_phy-thetao_anfc_0.083deg_P1D-m', ...
'cmems_mod_glo_phy-so_anfc_0.083deg_P1D-m'};
Because Mercator update their server, and you need to download data in another way...
Tell me if it helps you :)
