- Visit the Satlantic ProSoft webpage to download and install the post-processing software.
- Request Radiometer RAW data products from data search, download and unzip, creating a new working directory where ProSoft can create new files as it processes the raw data.
- Start ProSoft.
- Import instrument configuration and calibration: in the Processing Context / Current Instrument:
for profiling radiometers click Import, navigate to the working directory, select a CFS file;
for non-profiling radiometers click New, navigate to the working directory, select a SIP file
then press save once it's done reading the file. (If you've done this step before, select the Current Instrument you will be working on.) - Create a new/default Current Parameters, click New under current parameters, then Save As..., name it something like 'Default'. (You may create additional instances of Current Parameters and edit as necessary)
- For non-profiling radiometers, follow the normal processing flow, except you will probably need to exclude the SATMSG.tdf from the loaded calibration files (it was causing failures to read the data). You'll also need to choose the parameters in the both Current Instrument and Current Parameters to match the instrument and processing objectives, see the ProSoft User Manual for more information. When setting up the Current Instrument you can save and import a CFS file. Here's an example CFS file for the SAStracker: test3.cfs. Once everything is set up, select Multi-Level Processing Level 1 --> 3a and select the RAW files in working directory that you wish to process (we tend to go to Level 3a because that's as far as a default parameters will take you).
For profiling radionmeters, the processing flow is more complex: select Multi-Level Processing Level 1 --> 4. This will bring up a window to select the RAW file to process (locate the working directory, then 'Add' a file to process. Recommend only working on one file at a time, as each file is likely from a different cast, unless the files span midnight. This is essential: make sure that the name of the RAW file you select corresponds to the selected Current Instrument you wish to process - check the date range and serial number in the CFS file-name you loaded in step 4, select a RAW file that fits within the time range and matches the serial number (i.e. HOCR-R08W). For a download of a single cast segment, there are normally 2 CFS files and 2 RAW files, one pair for upwelling and downwelling radiometers. Additional CFS files are added only when necessary. If ProSoft asks to confirm the pressure tare initial value in a pop-up dialogue box, enter '0.0'. The pressure tare is always zero because our pressure values come from a calibrated CTD. - If there is a problem with the processing (ProSoft freezes), read the manual, see the following tips or contact us. We encourage our users to get familiar with the operation of ProSoft, see the ProSoft User Manual for more information. In addition, here are some tips to attempt to get ProSoft to work. Following the steps above, but instead selecting Single Level Processing, users should always be able to get to level 1b where calibrations have been applied. With the level 1b data, users can visualize and export the calibrated data (see the steps below). Level 1b --> 2 processing involves referencing, sorting and sequencing (deglitching). For a problem in reaching level 2, try turning off the 'Profile Edit' (this will disable exclusion of bad data). Also try turning off 'Deglitch Profiler Data'. Further, try restarting ProSoft, then investigate and experiment with the Current Parameters. For problems in level 3, experiment with the bin intervals - larger can work. For level 4, some products are not supported (especially for non-profiling radiometers and SAStracker). We've also found some problems with the progression of data in profiling radiometers; ProSoft appears to prefer individual casts where the radiometers are consistently moving up or down. Water depth variation due to surface waves may cause problems. Users may need to cut out some data at the top of casts by limiting the data search time range. User may also need to combine RAW files in ProSoft by processing these files together. As noted above, we may improve this data product by integrating cast delimitation so that we can provide RAW files that are much easier to process; including joining good data together, while eliminating difficult data.
- View or extract data from the HDF files produced, see the 'Tools' menu. Create ASCII data products, see the 'Ascii' menu. A quick look with the HDF data viewer is a great way to get an initial sense of the data.
- Repeat steps 4 thru 9 for the remaining RAW files.
