This page describes a quick route to the installation and use of SHICrivm for new users

We have now provided a standard installation for the EDUCE project which should make the programs easy to use. The package is contained in a zip-file and running requires the following 4 steps: 

step 1 unzipping the files and directory structure: unzip the files and directory structure.
Following installation the following main directory structure should exist:

step 2 copy the measured spectra and slit function to the appropriate directories set in shiccall

  • data in c:\SHICrivm\uvdata\LLL\
    (LLL: stands for three lettercode to identify the spectroradiometer (NLR-example is pre-installed));
  • DDDhhmm.LLL (example: 0861012.NLR ; two column format: column 1: wavelength (nm) ; column 2: irradiance (W/(m2.nm)) 
        DDD = daynumber of the year
        hh = hour of the day
        mm = minute of the hour
  • slit function in main analysis path: c:\SHICrivm\uvanalys\LLL.sli (NLR.sli example is pre-installed) 

step 3 Run SHICcall 
set the parameters for the specific instrument and the measurements to be analysed:  

  • DAYtime field: date and time of the measurements to be analysed (convention: DDDhhmm: see above) 
    in figure below all spectra of day 086 are selected
  • instrument-ID (LLL-code))
  • path + DFA-file name (file will be created by SHICcall, in example RIVM2002.dfa (file with parameter settings))

Use the settings button to adjust parameters like the year of measurement, the location (Latitude, Longitude in degrees decimal) settings on wavelength range of measurements (confirm changes by pushing apply buttons). Example of main settings page:

step 4 push the RUN button in the SHICcall main page.
Example of the SHIC3_075rivm.exe run-window.  

  • Run starts with version line: SHICrivm version….
  • Then gives the analysed filename (DDDhhmm.LLL, inthis case 0861124.nlr)
  • information on the estimated transfer in the UVA and UVB and the wavelength shifts in these regions
  • End of analysis indicates a successfull end of the run (this run was on a 300 MHz Windows NT-pc).
