[CF-metadata] CF Section 5.3 Reduced Horizontal Grid and Section 8.2 compression by gathering somewhat inconsistent

2008-10-11 Thread John Caron
CF Section 8.2 compression by gathering has this example: dimensions: lat=73; lon=96; landpoint=2381; depth=4; variables: int landpoint(landpoint); landpoint:compress=lat lon; float landsoilt(depth,landpoint); landsoilt:long_name=soil temperature; landsoilt:units=K;

One thing i forgot to mention, in the 5.3 example: Example 5.3. Reduced horizontal grid dimensions: londim = 128 ; latdim = 64 ; rgrid = 6144 ; variables: float PS(rgrid) ; PS:long_name = surface pressure ; PS:units = Pa ; PS:coordinates = lon lat ; float

[CF-metadata] ragged arrays vs compression by gathering

2008-10-11 Thread John Caron
I was looking at the reduced horizontal grid feature because its really a way to store ragged arrays rather than the somewhat more general compression by gathering. Its possible that a convention to store ragged arrays might be quite useful in point observation conventions that ive been trying
