Appealing NASA's FOIA Decision

I've decided to appeal the FOIA decision from NASA, JPL. To do this I have to write out a hard copy letter and snail mail it to the appeals office. Here's the copy of that letter:

Dear Sirs,

I'm writing this letter to appeal a FOIA decision involving NASA JPL. The decision involved 3 issues, the first of which has been resolved. For the second and third decision, I've included relevant background information as well as the reason I'm appealing.

Issue 1: Radiative Transfer Algorithm Used By AIRS.
Status: Resolved.

Issue 2: Atmospheric Scan Depth Of Aqua Satellite AMSU Channel 5 Footprints.

Background
The Aqua satellite has an AMSU instrument that scans the atmosphere at 15 different channels. Each of these channels scans 30 different locations in the atmosphere. These locations are sometimes referred to as "footprints". Each footprint scans at a different height in the atmosphere.

NASA Discussion On How This Data Is Used
Where reliable sensor data is available, it is applied directly to the appropriate portion of the atmosphere, taking into account the angle of the observation.
- Steven Friedman, NASA JPL, Personal Correspondance (Included)

My FOIA Request
(2) Atmospheric scan depth for each footprint on channel 5 of the AQUA AMSU.

FOIA Response
This is to advise that NASA has no responsive Government records at JPL for parts (2) and (3) of your request.

Why I'm Appealing This Decision
NASA JPL has indicated that they apply each scan to the appropriate portion of the atmosphere. This is impossible to do if it is unknown at what depth of the atmosphere a given footprint is scanning.

Issue 3: The 230000 Scan Readings And/Or The Values Of Vectors Ai And Theta Bar i Used To Synthesis Aqua AMSU Channel 4 Data

Background
Aqua's AMSU channel 4 failed in late 2007, as described in AMSU-A Channel 4 NeDT Update: 20 December 2007 at the document archive. The data for channel 4 is now artificially generated. The generation process uses two vectors, Ai and Theta Bar i. The values for these vectors is not available to the public. The data for the vectors was itself generated from 230000 scans taken from the AMSU. This data is also not available to the public.

NASA Discussion On How This Data Is Used
See AIRS/AMSU/HSB Version 5 Modification of Algorithm to Account for Increased NeDT in AMSU Channel 4 at http://disc.sci.gsfc.nasa.gov/AIRS/documentation/v5_docs/AIRS_V5_Release_User_Docs/V5-Modification-for-AMSU-Ch-4-NeDT.pdf for a detailed discussion on this data. In particular, see equation (1) for the use of Ai and Theta Bar i.

My FOIA Request
(3) In references to the creation of synthetic readings for the AQUA AMSU channel 4, the 230000 cases used to create the values for the vectors Ai and Theta Bar i, or the values of vectors Ai and Theta Bar i themselves if the 230000 readings are no longer available. These values and readings are referenced but not actually provided in the document AIRS/AMSU/HSB Version 5 Modification of Algorithm to Account for Increased NeDT in AMSU Channel 4 available online at http://disc.sci.gsfc.nasa.gov/AIRS/documentation/v5_docs/AIRS_V5_Release_User_Docs/V5-Modification-for-AMSU-Ch-4-NeDT.pdf..."

FOIA Response
This is to advise that NASA has no responsive Government records at JPL for parts (2) and (3) of your request.

Why I'm Appealing This Decision
NASA JPL has indicated that this data is used to generate the synthesized channel 4 data. This would be impossible to do if the values for vectors Ai and Theta Bar i were not known to them, as these values are two of the four values used to generate the synthesized data.

Note that NASA JPL also indicated that NASA GSFC may have responsive records for issue 3. I am in contact with them to see if this is the case, but as my ability to appeal this decision is limited to 30 days, I am simultaneously appealing.

Thank you for you time and help in this matter.

...and the e-mail sent to NASA, GSFC for the data used to generate synthetic channel 4 values:

I was informed by Dennis B. Mahon of NASA, JPL that NASA GSFC may have information regarding data used to generate synthetic channel 4 data for Aqua's AMSU channel 4. Specifically, I am looking for he 230000 cases used to create the values for the vectors Ai and Theta Bar i, or the values of vectors Ai and Theta Bar i themselves if the 230000 readings are no longer available. These values and readings are referenced but not actually provided in the document AIRS/AMSU/HSB Version 5 Modification of Algorithm to Account for Increased NeDT in AMSU Channel 4 available online at http://disc.sci.gsfc.nasa.gov/AIRS/documentation/v5_docs/AIRS_V5_Release_User_Docs/V5-Modification-for-AMSU-Ch-4-NeDT.pdf..."

See equation (1) of the referenced PDF for specific details.

Please note that this request is associated with a FOIA involving NASA, JPL that is currently under appeal.

  1. Hi,
    Your experiences over the US Government's apparent fraud in manipulation of satellite data mirrors the extraordinary evidence of malfeasance I have uncovered in my series of 'Satellitegate' articles.

  2. I am keeping my fingers crossed that you both keep digging into the data...

  3. They've lied to us before about the moon-landings.
    "Scientists" made billions from the Apollo Program.
    Now NASA is making trillions from the global warming conspiracy.
    Follow the money. Follow the money.

  4. My apologies for not being here for a while. There've been other things going on in my personal life that I've needed to attend to.

    Mr. O'Sullivan, all of my work has been placed in the public domain. This means you are free to use it as you see fit.

    However, I am not personally trying to demonstrate fraud on the part of NASA or any other scientists. I am simply trying to reproduce published claims and pointing out where the information made available to the public falls short of what's needed to do that.

    As a quick note, NASA responded to my FOIA appeal several months ago. They provided me with the values for the vectors Ai and Theta Bar i, which I hope to post here in the near future.

    However, they claim that there is no documentation in NASA regarding the atmospheric height of each foot print for each channel scan of the Aqua satellite. It's therefore still impossible to reproduce any of their claims.
