Wen,

The NEXRCOMP radar composite is distributed in the FNEXRAD data feed.
The GINI format products I create are current in the data feed. You
can check your ldmd.conf to see if you are requesting the data
from your upstream, and chek the rtstats pages to make sure your
upstream site is receiving the data.

The TAMU site has current GINI products in the 1km/n0r, 2km/n1p and
4km/NTP directories. The pqact.gempak_nexrad file has the FNEXRAD
pattern for these products.

The directories on the TAMU site that are old are the AREA file
directories for products that Tom Yoksas was creating from the GINI
composites mentioned above. My guess is that Tom's program did not get
ported over when the adde.ucar.edu server was changed. But, these are
not original data products, just reformating of the original GINI format
FNEXRAD products, so all the data is still available in the original
format. I'll let Tom know his AREA files are not currently flowing.
