I am running a land biosphere model that uses meteorological data as drivers. The model has a threshold of 32g/kg for specific humidity. The data I am using taken from a reanalysis performed by J. Sheffield at Princeton has some values of S. Hum. higher than 32g/kg. Given that such data is of resolution of 1 degree and 3 hourly interpolated from 6-hour data, what is a typical range for S. Hum. in lowland tropical areas. I need to know this to deem if these data is close enough to the real world or if it includes unrealistic values I will consult the author and point out that data might be inaccurate for these regions. It is difficult to find online any direct measurements, I only find these big data sets such as NCAR-NCEP.
edit: looking at a region of the Amazon, I see frequent values around the 30g/kg range, for example here http://iridl.ldeo.columbia.edu/SOURCES/.NOAA/.NCEP-NCAR/.CDAS-1/.DAILY/.Intrinsic/.PressureLevel/P/1000/VALUE/ds:/qa/temp//celsius/unitconvert/u/a:/v/:a/mag/:ds/%28qa%29//var/parameter/interp/nip/DATA/AUTO/AUTO/RANGE/P/1000/VALUE/T/0.0/dekadalAverage/X/-180/0.5/180/GRID/X/360.0/makeperiodic/Y/-90/0.5/90/GRID/X/Y/fig-/colors/grey/verythin/mews_prov/black/thin/countries_gaz/-fig//T/last/plotvalue//antialias/true/psdef/index.html?layers=countries_gaz&layers=qa&T=21-30%20Jun%202013&bbox=bb%3A289.775%3A-10.432%3A308.296%3A0.734%3Abb#instructions
