Hi Marcelo, Thredds team, We encounter the same issue at CLS! But our idea was more on the integer management. When a variable is a short or float, the tests we've done was ok. Waiting for the thredds opinion. Regards Tony Tony Jolibois C.L.S.

The data is stored as integer to save space and has a scale_factor: int sla(time, lat, lon) ; sla:_FillValue = -2147483647 ; sla:long_name = "Sea Level Anomalies" ; sla:standard_name = "sea_surface_height_above_sea_level" ; sla:units = "m" ; sla:scale_factor = 0.0001 ; I am not sure I can send the file for copyright reasons, but anyone with a subscription to CLS can get in ftp.aviso.altimetry.fr/donnees/ftpsedr/DUACS/global/delayed-time/grids/msla/all-sat-merged/h/1993/dt_global_allsat_msla_h_19930101_20140106.nc.gz when seeing the data using the Opendap protocol everything works and the values over land are show as missing. But when using NetcdfSubset or the Godiva2 viewer (that makes WMS requests) the values over land are show as valid but with two different values: -2.147e+5 in Godiva2/WMS and -2.147483647e+9 in NCSS. I think this is a similar problem as the one report by Peter Vodden in http://www.unidata.ucar.edu/mailing_lists/archives/thredds/2014/msg00002.html I tried changing the _FillValue (to -2.147e+5 and -2.147483647e+9) using ncml but that only made the Opendap start showing the land values as non-missing. Also tried adding attribute valid_min and valid_max but that didn't work also. Any ideas?
