## Instrument Status

- The TES instrument is operating normally
- Global Survey scheduled every other day
- Special Observations scheduled during ‘off’ days
- Over-velocity fault June ’08
- GS revised in response
- One Hundred Forty Global Surveys gathered YTD
- Eight Hundred Twenty Global Surveys since launch
- Five Hundred Eighty One Special Observations gathered YTD
- ARCTAS, OP3, WAVE 2008, Megacities (Tokyo, Lagos, Dhaka, Mumbai), China/Beijing Transects, Muana Loa (H20 isotope measurement campaign)
- One Thousand Six Hundred Fifty Five Special Observations since launch
- Instrument downtime this year:
- De-ice cycle commanded once on May 28 -30th
- ‘ICS only’ safe mode following an Over-velocity fault trip, June 9th.  Normal operation resumed June 13th.

## ICS GS Average Motor Current

**ICS GS Average Motor Current**

- Aura DSWG

- October 27, 2008

## Instrument Status – over-velocity fault

- Prior to June ’08 TES ICS motor current in steadily increasing
- Over-current events frequent
- Over-velocity events started Dec ‘07, culminating in over-velocity fault June ’08
- Modifications made to Global Survey ops
- Removed all long scans (1/orbit, intended for lube distribution)
- Removed observations below -60 south latitude
- Removed observations above +70 north latitude and -50 south latitude (total of about 30% reduction)
- Peak current much lower, average lower.....
- Idle motor current now higher; thought related to removal of long scans

## Every effort is being made to maximize instrument life-time while providing high science return
Extended science team has stated that sustaining the regular base of temporal sampling is vital, spatial modifications to the Global Survey are acceptable
TES is operating well within limits

## Data Production

- Three processing centers
- SIPS: processes Global Survey and Special Observations
- SPC: ‘special’ processing: full filter, larger scale science investigations
- SCF: supports development and small scale investigations
- SIPS:  260 nodes, 90 TB data storage – major upgrade scheduled
- SPC:  40 nodes, 10 TB data storage
- SCF:  40 nodes, 60 TB data storage – node upgraded this year

## Current State of Data Production

- TES GDS software version R10 completed reprocessing November ‘07
- TES GDS software version: ‘R11.2’, active at SIPS from late August ’08; all ESDTs incremented
- L1B ESDT Version 3
- L2 ESDT Version 4
- L3 ESDT Version 2
- Forward processed data from Sept 3rd uses GMAO 5.2, data prior to Sept 3rd 5.10
- File format designator on L2 HDF files incremented to indicate GMAO version

## TES Level 2 Data Version 4

- The Version 4 TES L2 data will include:
- Limb profiles valid into the upper troposphere
- Improvements to the temperature retrievals (updated CO2 spectroscopy)
- Improvements to the methane retrievals
- Species dependent quality control information
- Use of GMAO GEOS-5 products in L2 retrievals
- F05_05 in filename if GMAO GEOS-5.1.0
- F05_06 in filename if GMAO GEOS-5.2.0
- Data production began September 2008 (forward processing)
- Full reprocessing expected by mid-2009
- Preliminary validation analyses are underway
- ( from Greg Osterman’s Validation slides...)

## TES Web Page Redesign

_**New Functionality**_
**New look and feel using interactive links to  scientific content**
**Direct access to link for TES data ordering**
**TES Level 3 daily plots mapped using Google Earth**
**Update Science team bios**
**Access to all publications, presentations and posters generated since launch**

## TES L2 Time Trends

**TES Species Trend Plot - Tropospheric Ozone for     Northern-Central China   (Jan ’05 – June ’08)**

**This new TES web page provides access to pressure level vs time curtain plots for TES species (i.e. 0 O3, CO, ...) in a given region via a clickable world map.  Each profile on a curtain plot is the average of the profiles from either a Global Survey (< 26 hrs) or a Special Observation (minutes) over the defined geolocation area.    ****(http://tes/visualization/SCIENCE_PLOTS/Trends/world_map_clickable.html)**

## Issues & Other Items

- ESDT version for early R11 L1B & L3 data incorrect; redelivering data now
- Modified Global Survey twice in 2008 to reduce ICS usage
- 6/2008   Eliminated observation south of 60 degrees south
- 7/2008  Nadir observation bounded by 50 degrees south and 70 degrees north
- Future modification possible; determined by instrument performance
