[gradsusr] 2 questions about writing NetCDF output file

[Liu, Zhong (GSFC-610.2)[GEORGE MASON UNIVERSITY]]

Hi GrADS users,

I have two simple questions:

1) When outputting my data in floating (see below), how come the lat and lon arrays are still in double (other variables are in floating)? Is there any way to make them (lat, lon) floating?

'set sdfwrite -3dt -flt -nc4 -chunk -zip '%fn

I am using GrADS 2.1.a3.

2) For the 'Time' units, is there any way to overwrite for example ":units = "minutes since 1998-01-05 00:00";" with
"days since 1998-01-05"?

Thanks a lot!

Best,

Zhong Liu, Ph.D.
