[ncl-talk] SST plot with strange range

[Don Murray (NOAA Affiliate)]

Sorry, I didn't look at your attachments and now that I have, the data 
are definitely packed in shorts:

	short sst(time, lat, lon) ;
		sst:standard_name = "sea_surface_temperature" ;
		sst:long_name = "Monthly Mean of Sea Surface Temperature" ;
		sst:units = "degC" ;
		sst:add_offset = 0.f ;
		sst:scale_factor = 0.01f ;
		sst:_FillValue = 32767s ;
		sst:missing_value = 32767s ;
		sst:unpacked_valid_range = -5.f, 40.f ;
		sst:actual_range = -1.8f, 35.31f ;
		sst:precision = 2s ;
		sst:least_significant_digit = 2s ;
		sst:var_desc = "Sea Surface Temperature" ;
		sst:dataset = "NOAA Optimum Interpolation (OI) SST V2" ;
		sst:level_desc = "Surface" ;
		sst:statistic = "Mean" ;
		sst:parent_stat = "Weekly Mean" ;
		sst:cell_methods = "time: mean (monthly from weekly values 
interpolated to daily)" ;

In your script, call:

oisst  	= short2flt(in_oisst_f->sst)

when you read in the data.  Ferret must automatically apply the 
scale/offset - NCL doesn't.
