This sounds very interesting.

This data should be available in an archive of GOES image sectors that
were provided to users in the Unidata-Wisconsin (UNIWISC) datastream of
the Internet Data Distribution (IDD) system. The "rolling archive" of
these images does not go back to 2004 (it has about 9 months of the most
recent data only), but the images should be available in the larger tape
archive maintained by SSEC. FYI: the images in the rolling archive
available through the McIDAS ADDE server on unidata2.ssec.wisc.edu.
The dataset Group name is UNIARC.
Instructions for requesting data from this archive can be found in:

The last page referenced above has the information you need.
NB:
- When you send an email requesting that the data you are looking for
be restored from tape to disk, please let the folks at the SSEC Data
Center know that you were advised to request the data by Unidata User
Support (the archive is maintained for Unidata community members,
and UNAM is not (yet) one of these sites).
- Also, you said that you are interested in data for the infrared channel.
There are four infrared channels available in the archive:
GOES-East
3.9 um - shortwave infrared
6.5 um - water vapor
10.7 um - thermal infrared
13.3 um - longwave infrared
GOES-West
3.9 um - shortwave infrared
6.8 um - water vapor
10.7 um - thermal infrared
12.0 um - longwave infrared
It is most likely that you want the 10.7 um thermal infrared data, but
you may want others depending on what how you do your analyses. Please
be specific about which data you would like to access in your request
to the SSEC Data Center folks.
- The tape to disk restoration procedure may be such that all data from
one or more days is staged on disk for you to grab. If this is the
case, you will need to FTP the sectors that you are most interested
in.
- It is highly likely that it will not be possible to restore all of the
days of data you are interested in at once. In this case, you will
be given a certain amount of time to FTP the data that has been restored
before it is overwritten by additional data.
- It is possible that the archive does may have holes in the data record
(i.e., there may be some missing images)
- As you will see, the archive contains sectors from GOES-East and GOES-West.
The GOES-East sectors will have the best coverage for Mexico, but the
GOES-West sectors should be useful also.
re:

The archive mentioned above does not contain GINI format image sectors.
All the data in the archive is in McIDAS AREA format. We (Unidata) do
not archive the GINI image sectors distributed in NOAAPort. It is possible
that one or more Unidata community members has such an archive and would
be willing to provide access to it to you. We maintain an email list
named address@hidden for these sorts of archive data requests.

Very good. I suggest that you talk to your advisors about UNAM becoming
an active member of the Unidata community (its free!). This would allow
you (UNAM) access to a wide variety of software applications and data.
Cheers,
Tom
