DATA PROCESSING: Data from all systems will be transmitted to Biospherical 

 Instruments, Inc. where it will be processed to three levels: 



RAW DATA: Raw data will be archived after its transmission from the remote 

 sites. The data will be verified and scan parameters (start wavelength, stop 

 wavelength, and high-voltage and tube currents) will be specified. 



PRELIMINARY DATA: Data from each hourly scan will be processed with 

 calibration constants applied to provide information in approximately the 

 following forms: 



280 - 350 nm averaged over 1-nm increments 

 280 - 700 nm averaged over 5-nm increments 

 UV-B, UV-A, and PAR averaged hourly 

 Weighted observations using various action spectra 

 FINAL DATA: Data will be corrected annually, after each site has been visited 

 for an appraisal of the system's calibration stability. 



DATA DISTRIBUTION: Those interested in obtaining data should contact P. A. 

 Penhale.
