UV Product Files
UV data products having ascending levels of quality control (QC) applied to the data. As new improved QC algorithms are designed and implemented, new data files will be produced using the following file naming conventions:
| yyyy | Four-Digit Year 2000-2010 |
| DDD | Three-Digit day of year 001-366 |
| ssssss | Six-Character Station ID Code. First four characters denote abbreviation for a location. Last two characters denote a state code. TMTFCO repressents Table Mountain Test Facility, CO. |
| BBB | Three-digit serial number of a Brewer Instrument. Example: 101-154 |
| pp | Two-character code identifing the product. Examples: UV or UX |
| SCR | Three-Digit code identifing the quality control level applied to the data: S - Level of QC appled to the Signal or counts from the Spectrometer. C - Level of Cosine correction applied to the data. R - Level of Responsivity applied to the data. For instance: SCR=000 would denote file of raw data; SCR=111 would denote file where counts were corrected, cosine was corrected and responsivity was applied. SCR=212 would denote data with better count corrections and better responsivity estimate than SCR=111. |
| SCR | Description |
|---|---|
| 000 | Raw counts generated from B and UV Brewer Files. |
| 100 | Dark Counts applied to data |
| 101 | Irradiance obtained from the most recent CUCF responsivity. |
| 201 | Takes 101 data as input and applies strayilight correction and spike filtering. |
| 211 | Basic cosine correction that differentiate cloudy and clears sky only. |
| 312 | Irradiance obtained with interpolated (bracketed) two CUCF responsivities. |
| 313 | Responsivity based on CI trends and CUCF responsivities. |
| 323 | Cosine correction based on dir/dif values from collocated MFRSR’s. |
| 324 | Responsivity based on adaptive-predictive model of temperature dependence using MFRSR and other collocated instruments plus CI and CUCF data. |
| 325 | The same as 324 but anchored with biannual CUCF calibrations. |
Characterization
Brewer characterization files include;
- CUCF Lamp Calibration Data - data files and images about the precision lamps used to calibrate the NEUBrew Network Instruments for UV.
- CI Reference Scan Data - file containing the baseline reference CI Scan. These data are used to generate ratio plots of the Brewer's internal Halogen Quarts lamp
- Brewer Calibation Responsivity Data - data files containing the responsivity from all the UV calibrations that have been performed on the NEUBrew Network instruments.
Brewer Automatic Operation Schedules
To achieve autonomous operation Brewers require an operataion schedule. The schedules consist of a solor evevation angle followed by a string of one or more two-character subroutine commands on a single line. Numbers between 2 and 99 can be appended to the and of a command string to cause the command string to be repeated n-times (or until the next solar zenith angle is reached.) There are two forms of the schedule A and B. Examples of the A and B schedules are shown below:
| SCHEDULE A | SCHEDULE B |

Form A of the schedule runs four consecutive days, then B is run for one day, then the succession starts over as show in the Figure below:
The naming convention for schedule files is yydddFs:
where: yy = two-digit year, ddd=three-digit day of year, F=form A or B, s=sequence number 1-5.
yyyddd = the date timestamp the schedule was created.
NEUBrew Brewer Software
The Brewer software and sub-routines used by the NEUBrew Network instruments is based on the baseline version 3.75f software provided by International Ozone Services IOS. Several of the sub-routines have been modified to suit NEUBrew mission goals. New routines have been added to allow more flexibilty to the Umkehr sub-routine. UV and CI routines have been modified to allow the NEUBrew version of the Brewer software to run on Linux platforms and Windows XP. All the source code for the NEUBrew software, modified routines, and newly added routines can be found on our FTP server (click on the link above).
Brewer Raw Data Files
Brewer raw data files are provided as produced by the Brewer instrument and its internal procesing. No quality control have been applied to the data. Raw data are intended for diagnostic purposes only.
