Current Sample Files

During measurements, data files are automatically generated on an hourly basis when UNLIMITED mode is selected. This implies that data updates are available with a delay of at least 60 minutes when the files are remotely downloaded from the host (e.g. by an ftp server). Sometimes it is desirable to get updates more frequently. This is possible in the following way:
Enter the Define Continuous File Generation of Current Samples menu. For each product a separate file interval can be defined. This interval determines the file length of the current samples file. E.g. when a file interval of 10 minutes is selected for the Brightness Temperatures, a new file CSYYMMDDHHmm.BRT is created every 10 minutes (YY=Year, MM=Month, DD=Date, HH=Hour, mm=Minute of the date / time centred to the current CS file interval) and stored to the directory shown in the File Directory box on the left. The data in the current data files can be averaged by selecting a shifting average number (measured in samples). Integration times / sample and retrievals are taken from the MDF product settings. 
The CSYYMMDDHHmm.XXX file creation can be enabled / disabled by checking / unchecking the Enable Current Sample File Generation check box. The CSYYMMDDHHmm.XXX file format is identical with the standard binary file format of the products. Automatic ASCII file generation is enabled by checking the Add ASCII File check box. For CS Files the relative humidity can be blocked to be appended to absolute humidity files by un-checking the Append Rel. Humidity to HP-File check box.
In the case that One Sample / File is activated, the program stores only the latest sample of a file interval in the CS-file. The only exception is the *.HKD CS file which is not affected by this flag.
In the case that File Overwrite (Name:CS.XXX) is activated, the program is not using the  CSYYMMDDHHmm.XXX file convention. Instead, only CS.XXX file names are created, thus overwriting older files by the newest one.
When both ‘Temperature Profiles (full troposphere)’ and ‘Temperature Profiles (boundary layer)’ are selected from the list of products, a CS.CMP.TPC file is automatically generated. This file contains a composite temperature profile combined from the two CS.TPC and CS.TPB files. The temperature values below 1200 m altitude are identical in CS.CMP.TPC and CS.TPB and the same is true for the temperature values above 2000 m which are identical in CS.CMP.TPC and CS.TPC. In the altitude range 1200 m to 2000 m the CS.CMP.TPC file temperature values are generated from a cubic spline fit to match both profiles in CS.TPC and CS.TPB smoothly. The cubic spline interpolation ensures that the first and second derivative of the fit matches precisely the two profiles from which it has been generated.
