## **Mission Ops (Guit):** see distributed ppt file for details. 

[Major activities over last month:]{.underline}

-   March 1, 6: AMSR-E SPC error (observational parity error) flag
    anomaly. Both occurred in the South Atlantic anomaly region. The
    flag was not cleared using the standard procedure used for previous
    occurrences. With JAXA direction, commands were sent to clear the
    flag resulting in about 1 hr of data being lost (March 4
    01:35:36-02:31:49 UTC).

-   March 2: MODIS lunar cal #17.

-   March 25: Expanded DB coverage of northern CA coast for SeaSpace DB
    station (to last for 30 days).

-   March 26: Afternoon constellation WGM at LaRC.

-   March 31: Inclination Adjust Maneuver (IAM) #2; no results yet, but
    maneuver showed repeatability with IAM #1.

######## Planned Activities for Next Month

-   MODIS Lunar Cal: 4/1,30 ("blue" moon).

-   TBD: Star tracker time tag error fix. It is noted that MODIS is
    particularly interested in getting this done. The patch has been
    requested for early April.

-   TBD: McMurdo ground station test for SSR replay. Complicated because
    McMurdo doesn't have command control capability.

-   Further Finland DB testing. For testing Aura DB (requirement of once
    a day) and better DB to northern Europe sites.

[Future activities]{.underline}

-   June: CloudSat delta-mission review (early June) with review of Aqua
    IAM results/plans. Possible trip to Alaska ground stations for Aura
    launch support.

## Spacecraft Anomalies - OPEN

[]{.mark}

-   Performance vs. prediction difference noted during Inclination
    Adjust Maneuver (IAM) #1. Performance evaluation for IAM, #2
    (implemented on 3/31) is TBD. EL: Can you send information to Frank
    Wentz. BG: Yes. Also, FOT will put together a full report.

-   No change in status to following anomalies: Propulsion system, Solar
    Array Drive Assembly (SADA) potentiometer anomaly, and Star Tracker
    #1 Time Tag Error.

## Instrument Anomalies

[]{.mark}

-   AMSR-E 89 GHz anomaly. Waiting for closeout report from AMSR-E team.
    EL: US or Japanese team? BG: Either. Elena will will take this as an
    action item.

-   FOT will write closeout report on AMSR-E SPC error flag anomalies.

[Ground Station]{.underline}: Ground station anomaly chart in Guit ppt
file. Steady decline in anomalies since mission start. Three anomalies
last month (March).

[]{.mark}

[Spacecraft]{.underline}: status = green

[]{.mark}

[Instruments]{.underline}: status = green

[]{.mark}

[Data capture/L0 processing]{.underline}: status = green (capture rate
for March TBD). One hour of AMSR-E data lost during SPC recovery.

[Aqua Conjunction Analyses]{.underline}: Objects (debris) tend to come
within 2 km of Aqua 1-2 times per week (from Cheyenne Mountain
analyses). Close approach summary and tables shown in Guit ppt file.
Will be establishing process to do routine screening for Aqua and
A-train.

[Upcoming A-train launches]{.underline}:

Aura: launch scheduled for June 17 2003.

Parasol launch scheduled for December 15 2004.

CloudSat/CALIPSO launch scheduled for April 2005.

[Afternoon Constellation WGM (Kelly)]{.underline}: Had a productive
meeting. Will have a revised Operations Coordination Plan in about a
month for signatures of key players.

### **Project Science (Parkinson):**

Dot Zukor (GSFC) wanted input on how various Goddard projects can
support homeland security efforts. Claire mentioned MODIS dust and fire
as examples. Anyone else that has input, please pass along to Claire.
AK: U. of New Mexico is establishing a ground station to use MODIS data,
with some possible relevance to homeland security; will pass information
she has along to Claire.

Update to EOS reference handbook is in the works. Input from instrument
teams being solicited.

AIRS science team meeting this week. A highlight was hearing about
weather forecasting and data assimilation efforts, and improvements from
incorporating AIRS/AMSU data. CERES meeting is this week at NCAR.

Aqua POP (program operating plan) review occurred a few weeks ago.
Hoping that money is beginning to be distributed. Revised
budgets/statements of work were to have been written for reduced awards.

**Data system/EOSDIS (Lu):**

Data systems doing well.

**Science Working Group for Data -- SWGD (Wolfe):**

No report.

**CERES:**

No report. A CERES Science Team Meeting was held March 29-31 at NCAR.

**MODIS (Salomonson):**

Telecon this last Monday with algorithm science teams. Made progress in
getting contract awards established. Science team meeting will likely be
in early June. Still getting names for science team membership (up to
about 90 now).

Halfway through reprocessing Aqua data.

**AMSR-E (Lobl):**

New team member list has been provided, however there are another 6 or 7
that will be using AMSR-E data, and wondering why they aren't listed as
team members. CP: Possible issue is that new award winners may not have
checked AMSR-E team on proposal submission. Also, HQ may still be
updating team member lists. EL: wrote email to Ramesh (2 weeks ago) to
request the addition of these people. If added, team will be up from the
original 7-8 members to about 17.

At last month\'s meeting in Japan, JAXA agreed to allow AMSR ADEOS-II L2
and L3 products (processed with US science team algorithms) be archived
at the NSIDC, and be made available to the public with no restrictions.
Lower level products, Level 1A and 2A, will only be available to a
restricted distribution (NASA HQ would give access approval). Glenn
Iona, with input from E. Lobl, D. Conway, and M. Marquis, is drafting a
Letter of agreement between NSIDC and JAXA defining the terms of
archival and distribution for these products.

AMSR-E L2, L3 products processed with US Science team algorithms went
public on March 1. Everything went well. The AMSR-E SIPS will start
processing data from the beginning of the mission to March 1 2004, no
earlier than April 15, 2004.

Would like to have an August/September science team meeting.

Wakasa Bay workshop is being scheduled for Ft. Collins in August
(campaign participants only).

### **AIRS/AMSU/HSB:**

No report. An AIRS Science Team Meeting was held March 30 through April
1 in Greenbelt.

### **HQ (Kakar):**

No report.

**Outreach, web site, etc. (Graham):**

Nothing to report.

**Next Telecon:** Thursday, May 6, 2:00 PM.

Minutes are being placed on the following site:

Steve Platnick.
