MTP File Structure

All MTP data analysis files are located in a single folder named MTP on the root drive. It will be assumed to be the C: drive, althought this need not be the case.

File Path	Purpose	Examples, Comments and Notes
C:\MTP\	Root of MTP file structure
C:\MTP\Data\	All the data analysis files
C:\MTP\Data\DC8\	Files for all DC8 Campaigns/Missions	Folder also exist for ER2, WB57, M55, Ground

However as the number of different extensions increased, more and more extension name conflicts occurred with commerically available software filename extensions. To avoid these conflicts, we decided to rename them as shown above so they all have .TXT extensions (appropriate for ASCII text files). They are still referred to as "CAL files", "NUM files", etc, even though they are technically now "TXT files."

PAVE_NUM.TXT
NUM files contain three columns of information:

Column 1 is the flight number (in this example giving the year (05), campaign number in year for the aircraft (01), and the consecutive flight number for the campaign(02). (Flight 01 does not appear in this list because it was a pilot proficiency flight on which the instruments were not operated.)
Column 2 contains the flight date in YYYYMMDD format
Column 3 contains the flight objective

It is used frequently batch processing activities, such as producing a histogram of level flight segments.

PAVE_HDR.TXT
This is the header record template needed to write a Gaines-Hipskind format ASCII file that can be submitted to a data archive for a particular campaign. The MTP archive files have been assigned a prefix "MP," so MP-files are known to the research community as MP-files. An MP file has the filename structure:
MPYYYYMMDD.AC, where AC is an assigned extension for each aircraft (e.g., MP20050131.DC8).

Here's a brief free-form tutorial on how to decipher the MTP data: Data groups
   consist of the following group of lines per 15-second observing cycle.
First line is: UTSEC, number of retrieval levels in following table, Pressure
   Altitude, Pitch, Roll, Outside air temp (K), tropopause altitude #1 (km),
   tropopause altitude #2 (km) [if present], potential temperatures of tropopause
   #1 and #2, latitude, longitude, & lapse rate near flight level.
   The 1-liners (for each cycle) can be stripped & imported into a spreadsheet
   for convenient plotting of trop altitude, lapse rate, etc. The tropopause
   altitudes are calculated by cubic spline interpolation of the retrieved
   altitudes using the WMO definition (that is, trop #1 is lowest altitude
   where average lapse rate > -2 K/km from initial -2 K/km point to any point
   within 2 km; trop #2 occurs above first trop after lapse rate is < -3K/km
   for >1 km, and then first trop definition applies, possibly from within
   the 1 km region.)
Remaining set of lines for each cycle consist of 5 columns: col#1 is pressure
   altitude (meters), col#2 is temperature from MTP (Kelvin), col#3 is temperature
   error estimate (K), col#4 is geometric altitude (meters), based on ICATS GPS
   altitude (meters), and col#5 is molecular air density [1E+21/m3].

PAVE_RMS.TXT
This file contains the observable errors for the campaign. The data are arranged in the order elevation angle 1 through 10 for channels 1 through 3. These errors are used as the a priori errors when the multiple linear regression is done to calculate retrieval coefficients. It is very important that these errors are realistic; otherwise, the data will be either over- or under-utilized. These errors are estimated when the Window Correction Table is calculated.

PAVE_WCT.TXT
Before brightness temperatures can be used in a retrieval, one final correction must be applied: the window correction table or WCT. When measured brightness temperatures near a radiosonde launch site are compared to the expected brightness temperatures based on the radiosonde temperature and humidity profile, small differences are seen that have a clear and repeatable dependence on elevation angle and frequency. These differences are generally <1 K, but can become larger for high altitude aircraft at high viewing angles because atmospheric transparency becomes important. The window correction appears to be very stable during a campaign, but can change when the instrument is remounted. It is believed that most of the window correction is due to beam sidelobes viewing different thermal structure inside the fairing as the scan mirror moves. There may also be a component due to LO leakage and reflection from the HDPE window, which is why these corrections were named window corrections. On some campaigns the window correction appears to have a pressure altitude dependence, but this is not always the case. The lowest frequency measurements always have a much larger window correction than the higher frequencies, and this has successfully been modelled as being due to waveguide cut-off, which is attenuating the signal at the longest wavelengths.

When window corrections were first calculated, it was a very tedious spreadsheet process, taking a day for just one comparison. The reason for this was that many checks need to be made to minimize errors. Only level flight segments can be used to avoid temperature changes due to the lapse rate of the atmosphere. Also for this reason, tropospheric comparisons need to be avoided if possible because of the high lapse rate there. Implicit in the desire for level flight segments, is the need to avoid pitch and roll changes, which can result in pointing errors and hence measured temperature errors. Changes in the outside air temperature are also monitored to avoid large temperature changes due to flying through fronts or other causes. Several scans are also averaged to minimize retrieval noise, and these scans should be contiguous to avoid the effects of real atmospheric temperature gradients. This means that that the retrieval quality flag must be checked for possible interference, and the process restarted if there is. In addition to checking the quality of the measurements, it is also necessary to check the quality of the radiosondes being used.

Calculating window corrections has been automated by programming the process, rather than doing it manually in a spreadsheet. The spreadsheet phase however was important because it helped identify the precautions that were necessary to achieve reliable results. Although some effort is needed to set up the calculations, dozens of radiosonde comparisons can now be done in seconds. When the window corrections are calculated, there is noise on their estimate. As will be discussed in the following section, this noise is included in the a priori observable error that is needed to calculate retrieval coefficients.

The data in the WCT is arranged by elevation angle and frequency channel. Note that when the WCT is calculated, the horizon value is forced to be zero so that the calibrated horizon temperature is not modified.

PAVE_FLA.TXT
This contains the list of flight altitudes (km) for which retrieval coefficient sets are calculated. For years standard altitudes were used for each aircraft, which could lead to interpolation errors if the levels were not close enough together. There is now a process on the MTPbin Tools forms Run Pgm tab that automatically goes through all the flights for a campaign to identify all the level flight segments. This produces a text file (e.g., PAVE_LevelFlight.txt) which can be imported into a spreadsheet (e.g., PAVE_LevelFlight.xls) to generate a histogram of the level flight segments. This is then used to identify the most commonly flown flight levels, which are then entered into the FLA-file (e.g. PAVE_FLA.txt) for subsequent use.

PAVE_IFB.TXT
After January 28, 2006, the sensor unit name (up to 4 letters) would have been included in the filename as well because the ER2-like sensor units fly on multiple platforms. This was not so much an issue early on when the IFB file would have been save in the C:\MTP\Setup\ folder. Now that we have moved the IFB file the the C:\MTP\Data\PLATFORM\MISSION\Setup\ folder, including the sensor unit name avoids possible confusion. There this file would now be named PAVE_DC8_IFB.TXT. The IFB file also used to assume that the IF bandpass was the same for each channel. They are slightly different, so three header lines have been added to specify:
The Number of IFB Channels (1 or 3) - old files have only 1
The Number of sub-channels in the model for each bandpass
The Percent Waveguide Roll-off in each IFB Channel - normally only the LSB of Channel 1 has this correction
The Sub-channel number, Center Frequency LO-Offset (MHz) and Sub-channel strength
Etc.

Hardware.INI
Note that the [RC_ER2], [RC_DC8], etc. categories in the Hardware.INI file are no longer used as the software now searches the RC folder in the MISSION path to find out the names of the available RCF files. The original RC file format including an CFG file and individual files for each flight altitude are still written in the C:\MTP\RAOB\Missions\MISSION\RC\ folder, but generally not used, and therefore not transferred to the C:\MTP\Data\PLATFORM\MISSION\RC\ folder.
