Re: list output

[Jonathan Callahan <callahan@xxxxxxxxxxxxx>]

Arne,

Here's an example using the COADS SST time series from CDC.  In it I
define a new variable which resets the value of the bad flag and use the
/FORMAT qualifier to the LIST command.

yes? use
"http://www.cdc.noaa.gov/cgi-bin/nph-nc/Datasets/coads/1degree/global/enh/sst.mean.nc";
yes? set region/x=180:190/y=0:10/t="15-jan-1961"
yes? shade sst
yes? let mysst = if sst then sst else 99.99
yes? list/format=(10f6.2) mysst
             IF SST THEN SST ELSE 99.99
             LONGITUDE: 180E to 170W
             LATITUDE: 0 to 10N
             TIME: 01-JAN-1961 00:00
             DATA SET:
http://www.cdc.noaa.gov/cgi-bin/nph-nc/Datasets/coads/1degree/global/enh/sst.mean.nc
 99.99 99.99 99.99 99.99 99.99 99.99 99.99 99.99 99.99 99.99
 99.99 99.99 99.99 99.99 99.99 99.99 99.99 99.99 99.99 26.00
 99.99 99.99 99.99 99.99 99.99 99.99 99.99 26.00 26.00 99.99
 99.99 99.99 99.99 99.99 99.99 99.99 27.00 99.99 99.99 99.99
 99.99 99.99 99.99 27.00 99.99 27.00 99.99 99.99 28.00 28.00
 99.99 99.99 27.00 99.99 99.99 99.99 99.99 28.00 99.99 99.99
 28.10 27.53 27.00 27.71 27.75 29.00 27.60 99.99 99.99 27.50
 99.99 99.99 99.99 27.00 27.80 99.99 99.99 27.21 99.99 27.00
 27.00 27.00 27.30 99.99 99.99 99.99 99.99 99.99 99.99 99.99
 28.00 99.99 99.99 99.99 99.99 99.99 99.99 99.99 99.99 99.99
yes?

Note: low latitudes appear at the bottom of the image but at the top of
the listing.

I could have used the original SST variable and

yes? list/format=(10g) sst

to get the bad flags to appear as their floating point values instead of
"***".
