Now Available:
AGAPE -- The Atmospheric Grid
Analysis and Profile Extraction tool allows you to extract and download
profiles based on instrument, location, date, and height.
You can also slice 2-D grids from the profiles and generate color maps
of atmospheric parameters (refractivity, temperature, pressure, and water
vapor pressure).
Mon, 17 Mar 2003:
We have migrated GENESIS data publication from the old anonymous-ftp
server to an account-based ftp server. Please
register for an account to access GENESIS data on
new FTP server.

JASON-1
GPS space data is available for download.
Repository:
We have established a central repository
for all publications related to:
- scientific results obtained with radio
occultations
- GPS applications in remote sensing
- GPS geodesy
- radio occultation techniques
- tomography and data assimilation
- improvements of the retrieval technique
- other related topics
Authors of any and
all affiliations who are interested in having their
preprints or publications posted on our site, please contact us
and send a pdf version of the paper. Links and
references to published papers are also valid as long as
there is no copyright infringement.

2002
Spring AGU meeting, Washington, DC.
23 April 2002:
The command was sent yesterday to switch
from the "B"-side electronics to the "A"-side. The data
from that side looks fine. The task now is to update the
SW from the May 2001 version now on the A-side. After
the SW is up to data, the tracking will be compared to
the recently deteriorated B-side data. This SW update
will take all week. We shouldn't expect to see any new
SAC-C tracking or occ data until the SW update is
complete.
3 March 2002:
A major software upload was attempted on
January 29th. 2002 to enable ionospheric occultations in
SAC-C. The upload included improvements in the scheduler
of the non-occulting satellites, a decrease in the
number of resets, and enabling ionospheric occultations.
The upload had to be interrupted and could not be tried
again until March 03. Occultation data are thus not
available for the time between the two dates.
Occultation tracking had been left on, but the receiver
was unable to acquire them until the upload could be
completed.
29 Oct 2001:
Testing new data acquisition modes on
SAC-C. Receiver and data formatting Software are getting
frequent changes. Although SAC-C data flow will stop
during the tests, usable data from this period will
appear under genesis probably by mid-January
2002.
