"NASA unveils new 'NATURAL HAZARDS' web site"

NASA UNVEILS NEW 'NATURAL HAZARDS' WEB SITE

NASA unveiled a new Web site today in which it publishes satellite
images in near real time over natural hazards around the world.  A
new addition to NASA's Earth Observatory, the Natural Hazards section, 
contains images and information about major environmental events that 
are potentially hazardous to human populations.

Initially, the Earth Observatory team will track five categories of
natural hazards: wildfires, severe storms, floods, volcanic
eruptions, and major air pollution events (dust storms, smog, and
smoke).  The images-acquired by NASA Earth Science Enterprise and
Earth Observing System (EOS) satellite missions-are freely available
to the public as well as news media.

"We are pleased to be able to share these spectacular new images with
the world in a timely manner," said Michael King, EOS senior project
scientist at NASA's Goddard Space Flight Center.  "We are often able
to publish these images within a matter of hours after they are
acquired by the satellite sensors."

"We believe the combination of high quality and moderate to high
resolution of the scenes we publish demonstrates the significant
technological advancements NASA has made in the design of satellite
remote sensors," King continued.  "We hope the public finds the
images informative as well as useful for educational purposes."

Earth scientists around the world use NASA satellite imagery to
better understand the causes and effects of natural hazards. The goal
in sharing these new images in the Earth Observatory is to help
people visualize where and when natural hazards occur, and to
possibly help mitigate their effects.

There are plans to expand the section's scope to include other types
of natural hazards information, such as earthquakes, coastal erosion,
and landslides.  The Earth Observatory is managed by the EOS Project
Science Office, and funded by NASA's Earth Science Enterprise.

The Earth Science Enterprise is a long-term research program
dedicated to understanding how human-induced and natural changes
affect our global environment.

"Positive News" on UARS Mission
in Satellite data
Message forwarded from Dr. Charles H. Jackman, NASA/Goddard Space Flight Center.
================================================================================

October 25, 2001

UARS Colleagues:

We have generally positive news to report.  Please send this on to
others as I may not have everyone on my UARS distribution list.

The latest news regarding the UARS Mission is given below:

MEETING AT NASA HEADQUARTERS ON OCTOBER 24TH - We had a meeting yesterday at

NASA Headquarters with Mike Luther (Deputy Associate Administrator)
and others in Code Y.  We discussed the status of the UARS and the many
changes that are ongoing in the project as well as this option.
Generally we received positive feedback.  We have been told to proceed
with the "Traceability Mission" option (see below) for the foreseeable
future.  The total cost of the "Traceability Mission" option including
mission and science operations is about $3.7M.  For comparison, the cost
of the UARS mission and science operations was about $15.4M in FY01.
We have received $2M so far that is being applied to the mission
operations.

UARS "TRACEABILITY MISSION" OPTION - This option will be primarily
focussed on providing validation/calibration measurements for upcoming
future missions.  We hope to provide UARS validation measurements for
the following future FY02 missions: TIMED, SAGE III, ENVISAT-1, ADEOS II,
EOS Aqua, and SORCE.  If we are successful in FY02, it may be possible
(with Code Y approval) to continue for an additional time period beyond
September 30, 2002, and overlap other missions.

UARS INSTRUMENT DATA COLLECTION - Instrument science observations
resumed on October 1st after being shutdown from September 24-30.
We are now in a "baseline operational mode" wherein we have 15 contacts/day
(once per orbit) as compared with 30 contacts/day (twice per orbit)
in FY01.  This allows the collection of about 20-30% of the possible
data.  Since the HALOE instrument uses the remaining working part
of the tape recorder, practically all of the HALOE observations are
being collected.  There is enough power to operate HALOE on about
2/3rds of the days.  After the launches of new missions, with an
appropriate time for outgassing and new instrument checks, the UARS
instruments will be operated in an "intense validation/calibrational
mode" for two-week observational periods.  During these periods,
the UARS instruments will have 30 contacts/day so that 50-55% of the
data would be collected.

UARS CENTRAL DATA HANDLING FACILITY (CDHF) - Unfortunately, we will not
be able to fund the UARS CDHF beyond November 30, 2001.  The UARS CDHF
is in the midst of final reprocessing, data archive, and supporting
the effort to move to data distribution through a "new" system called
PACOR-A.

UARS LONG-TERM DATA ARCHIVE - This issue is currently being addressed.
It is hoped that ultimately all the UARS data (including L0/L1/L2)
will be moved to the DAAC and be compatible with UNIX machines.  To
complete this effort will require some funding beyond what has been
approved.

UARS RETRIEVAL - It was decided at the meeting yesterday that there
will not be a Space Shuttle retrieval of the UARS.

Thanks for your support.  I am convinced that the community efforts over
these difficult several months.

Sincerely,

Charles Jackman
UARS Project Scientist

UARS Instrument Operations to Cease on Sep. 30, 2001
in Satellite data
Message forwarded from Dr. Charles H. Jackman, NASA/Goddard Space Flight Center.
================================================================================

July 23, 2001

UARS Colleagues:

We have some "Very Sad News" to report.

We were informed on Friday, July 20, 2001, that a final decision to
shut off UARS instrument operations on September 30, 2001, has 
been made at NASA Headquarters.  Given the positive response that we
received at our May meeting with Jack Kaye, Ghassem Assarar, and
Mike Luther, we thought that UARS measurements would continue for at 
least part of FY02.  We were encouraged to develop a minimum cost plan
for operations through December 31, 2002, and this had been our principle
activity up until Friday.

We were totally surprized and extremely disappointed by this decision
and we don't know if anything can be done to reverse this decision.  

No final decision has yet been made concerning the disposition of the
UARS and it is still possible that a retrieval will occur.  Also, there
has yet been no final decision concerning the final archiving of the
UARS data.

It is possible that this message is not reaching everyone with interests
in the UARS.  Please send it on to anyone who you think might need to
be informed about this decision.

This is all the information that we and Mike Kurylo (UARS Program Scientist)
have at this time.  We will inform you if we hear any other information.

Sincerely,

Charles Jackman             and         Anne Douglass
UARS Project Scientist                  UARS Deputy Project Scientist
