I am working with a netcdf of global drifter data <
http://www.aoml.noaa.gov/phod/dac/dac_meanvel.php>
that appears to have a non-conventional missing value.
Changing
setfileoption ("nc", "/MissingToFillValue/", False) ; turn off
to
setfileoption ("nc", "MissingToFillValue", False) ; turn off
allowed me to run my code and turn up the fact that the coordinate units
for the netcdf file are also non-conventional.
Error returned on run:
Variable: Latitude
Type: double
Total Size: 2536 bytes
317 values
Number of Dimensions: 1
Dimensions and sizes: [Lat | 317]
Coordinates:
Lat: [ -73.. 85]
Number Of Attributes: 4
long_name : Latitude (negative = south)
units : degrees
valid_min : -73
valid_max : 85
(0) check_for_y_lat_coord: Warning: Data either does not contain a
valid latitude coordinate array or doesn't contain one at all.
(0) A valid latitude coordinate array should have a 'units' attribute
equal to one of the following values:
(0) 'degrees_north' 'degrees-north' 'degree_north' 'degrees
north' 'degrees_N' 'Degrees_north' 'degree_N' 'degreeN' 'degreesN' 'deg
north'
(0) check_for_lon_coord: Warning: Data either does not contain a
valid longitude coordinate array or doesn't contain one at all.
(0) A valid longitude coordinate array should have a 'units'
attribute equal to one of the following values:
(0) 'degrees_east' 'degrees-east' 'degree_east' 'degrees east'
'degrees_E' 'Degrees_east' 'degree_E' 'degreeE' 'degreesE' 'deg east'
It looks like I need to reassign the coordinate variable units as well
as the missing value, and write them to the file. No need to reply if
this is a correct solution.
Thanks and Best Fishes
