Products + Integration

On the Products + Integration sheet, the user selects the products he wants to be acquired and calculated by the system. Only those products are enabled in the product list, which are compatible with the actual radiometer configuration, e.g. for a RPG-HUMPRO radiometer, all temperature profiling products are disabled. 
For those products with associated retrieval files, the user can select one of the retrievals listed in the related list box. The entries of these boxes reflect the data base that is currently available or applicable, e.g. LWP retrievals exist in three versions: one for two channels (for 23.8 and 31.4 GHz, RPG-LWP radiometers), one for three channels (23.8, 31.4 and 90 GHz, RPG-LWP-U90 radiometers) and one using 7 water vapour line channels (22.24, 23.04, 23.84, 25.44, 26.24, 27.83 and 31.40 GHz, RPG-HATPRO / HUMPRO radiometers). 
When the user of a RPG-LWP radiometer defines a MDF, the only retrievals that will be listed in the LWP retrieval list box are those for two channels. If he upgrades to a RPG-LWP-U90, the three channel retrievals are also listed. 
Right clicking on one of the retrieval file entries opens a text window displaying the retrieval file contents. A description of retrieval files and how to create them is given in the retrieval editor help message. Modifications of these files should be restricted to qualified personal only. Otherwise the modified retrieval algorithm may not work properly. 
For each enabled product, a separate integration time is selectable, but there is an exception: It is not possible to define a different integration time for the Brightness Temp. (boundary layer) and Temperature Profile (boundary layer) products because these products are closely related to each other. In fact, the temperature profile is just a further processed product derived from the brightness temperatures of the boundary layer scan. The user may define a customized Tmr retrieval and overwrite the default radiometer Tmr retrieval. If specified and checked, the new retrieval is used for sky tipping calibrations. For explanations on Tmr see the operating manual, section 4.5. 
Boundary layer scans can be combined with full troposphere temperature profiling in a single measurement. If only boundary layer scans shall be carried out, select the CONTINUOUS entry in the TP-BL Repetition list box; only boundary layer profiling data, meteorological sensor data and infrared radiometer data (if installed) will then be produced. All other selections in the TP-BL repetition list box define a repetition period for boundary scans. After a BL scan has finished, the other products like LWP, full troposphere temperature profiles etc. are generated and continue, until the next BL period is initiated. Example: Define a TP-BL repetition period of 600 seconds and an integration time of 200 seconds for the Temperature Profile (boundary layer) product. At measurement start, a BL scan is carried out which takes about 200 seconds. The next scan will start 400 seconds later. In the meantime the other selected products are processed.
The boundary layer scan can be performed in four different modes, selectable from the Boundary Layer Scan Mode box. The radiometer is usually scanning in the main quadrant (marked by a red arrow) but it is possible to switch to the opposite quadrant (called 2nd quadrant). Two scans in both quadrants can be averaged and combined into a single BLB scan (Bilateral average). But the two scans in the different quadrants can also be stored independently (Bilateral, two scans).
The Housekeeping Data product represents a summary of different parameters characterizing the instrumental state. These parameters are grouped into 6 categories (see help text for Housekeeping Data  Specify).
