[gradsusr] WAFS GRIB2: Cannot contour grid - all undefined values

Jennifer,

This fix worked great for me when testing lev 400, but I have scripted to make images for all levels and only levels 350 and 400 work. For levels 300, 250, and 200 I am still getting this error:

"Data Request Warning:  Request is completely outside file limits
  Entire grid contents are set to missing data
  Grid limits of file:     X = 1 288  Y = 1 145  Z = 1 10  T = 1 1  E = 1 1
  Grid limits of request:  X = 1 288  Y = 1 145  Z = 9 9  T = 1 1  E = 1 1
  Warning issued for variable = catmaxprs
Cannot contour grid - all undefined values"

it says im out of the range, but it clearly shows I am not. Any ideas here?

Jennifer,

That works for me! Thank you so much for the help as I have been banging my head over this for days.

I added the additional zdef levels (to make a total of 10) and then added the additional "3" to the grib codes and it works great now.

Thanks again,
Matt

Hi, Matt -- 
A few changes need to be made to your descriptor file. There are more than 6 pressure levels, so change your ZDEF statement to:

zdef 10 levels 80000 70000 60000 50000 40000 35000 30000 25000 20000 15000

Not all variables are defined at all these levels, but this set of levels is the superset to catch all the records in the file. 

Also, you need to add one more grib code to the units field in your variable declarations:

CBHEclm     0,10,0  0,6,25      ** entire atmosphere Horizontal Extent of Cumulonimbus (CB) [%]9,
ICAHTcbb    0,11,0  0,3,3       ** cumulonimbus base ICAO Standard Atmosphere Reference Height [m]
ICAHTcbt    0,12,0  0,3,3       ** cumulonimbus top ICAO Standard Atmosphere Reference Height [m]
CATaveprs   10,100  0,19,22,0,3 ** (400 350 300 250 200 150) Clear Air Turbulence (CAT) [%]
CATmaxprs   10,100  0,19,22,2,3 ** (400 350 300 250 200 150) Clear Air Turbulence (CAT) [%]
CTPaveprs   10,100  0,19,21,0,3 ** (700 600 500 400 300) In-Cloud Turbulence [%]
CTPmaxprs   10,100  0,19,21,2,3 ** (700 600 500 400 300) In-Cloud Turbulence [%]
ICIPaveprs  10,100  0,19,20,0,3 ** (800 700 600 500 400 300) Icing [%]
ICIPmaxprs  10,100  0,19,20,2,3 ** (800 700 600 500 400 300) Icing [%]

These changes resulted in a "MATCH" for all records in your file, using gribmap (in verbose mode) in GrADS 2.0.2.
