Input files

STRATO.INI :   Initialization file
It contains information about the site of the balloon launches, some information about the local computer system, and some analysis settings. STRATO knows about some launch sites, but of course not all. The geographical information are important, since they go into the analysis of the data, i.e. STRATO calculates the position of the sun and corrects the temperatures for a radiation error. If this file is not present, default values are assumed and the file STRATO.INI is created, which maybe edited later for reprocessing or proper configuring. This file is stored in the working directory.

Vnnnnnnn.CAL : Vaisala calibration file (nnnnnnn = the last 7 digits of the Vaisala serial number)
This file contains the calibration data provided with each Vaisala RS-80 radiosonde. The data must be entered exactly as printed on the calibration strip, no blanks, no empty lines. This file should be either in the current working directory, the directory /VAIS, or on the A: drive. The program will not run if no Vaisala file is found and will run improperly if the wrong Vaisala file is used. If the program can't find the Vaisala file, it is sufficient to put a floppy containing the file into drive A: and to try again. It is not necessary to halt the program and copy the file. The length of the Vaisala calibration file tells Strato, whether an H-type or and A-type humicap sensor is used (sample file).

xxnnn.RAW: Raw data file (xx = Station code, nnn = sounding serial number)
The raw data file created by STRATO in the recording mode is used as input for reprocessing of the flight data. This may be necessary, if some parameters are found to be incorrect after the sounding.


If provided, STRATO uses the files:

xxnnn.DE1: Description file created by STRATO
This file contains all parameters used in this flight. This file must be present in the working directory, or if configured, in the directory that contains the raw data.

PUMP.DAT : Pump calibration correction factors.
The proper coefficients are calculated within the program and stored in the description file. If PUMP.DAT is supplied it is searched for the correction factors of the ozone sonde given in the field ozone sonde number. The correction factors are assumed to be measured at 100, 50, 30, 20, 10,  7, and 5 hPa. If the sonde is not found or the file not specified a default value for the pump correction is used. This file must be present in the working directory.
