>1. Principal Investigator: Francisco P. J. Valero >2. Institution: Scripps Intsitution of Oceanography University of California, San Diego >3. Instrument (include brief physical description and > explain function): 1) Total Solar Broadband Radiometer (TSBR) 2) Fractional Solar Broadband Radiometer (FSBR) 3) Total Direct Diffuse Radiometer (TDDR) All of the above instruments are hemispherical FOV radiometers measuring downwelling radiation at the ground. The TSBR covers a bandpass of .26-4.0 microns. The FSBR covers a bandpass of .69-2.9 microns. The TDDR has 7 spectral channels at .500, .862, 1.064, 1.250, 1.500, 1.650, and 1.750 microns, each having a bandpass of approximately .01 microns. >4. a.

Names of personnel who will be working at the site: Brett Bush Shelly Pope Sabrina Simpson Piotr Flatau Francisco Valero Anthony Bucholtz Ginger Beriones Trevor Lillie >10. Requested instrument location (near central facility, > etc.): Our first request is to locate the instruments on the platform of the trailer just north of the SIROS cluster (as was the case in the Fall 1994 IOP). Our second option is to have them located in the same location during the Fall 1995 ARESE campaign (immediately adjacent to the SIROS cluster). Our reasons for relocating them is to minimize the amount of dust and dirt that the ground station data acquisition system is exposed to as well as making the monitoring of the station more comfortable to those involved. This relocation would also make the ground station much more "tornado proof" per the sentiments relayed during the recent San Antonio ARM meeting IOP coordination breakout session. Should the first option be granted, we request to be able to mount the three instruments to a semi-permanent platform (for the duration of the IOP). The data acquisition system can be located inside the trailer provided the conection to the radiometers can be made via the 19 foot cables. In the case of the second option, the platform used in the Fall 1995 ARESE campaign is adequate. >11. Site Support > > a.
