1.  Principal Investigator: Kenneth Sassen

2.  Institution: University of Utah

3.  Instrument: The University of Utah scannable 95 Ghz polarimetric
Doppler radar is designed for the study of clouds (e.g., cirrus and cold
stratus) not normally detected by conventional radars operating at longer
wavelengths.  The radar can not be exposed to significant precipitation,
and so is wheeled in and out of shelter to collect data.  The purpose of
the current field program is to collect supporting in situ and multiple
remote sensor data for use in the validation of remote sensing
techniques/algorithms for retrieving various cloud microphysical and
radiative quantities, and to increase our general understanding of
contrails and cirrus clouds.

4.  a.  Collect remote sensing data from high level clouds during the
operations of the UAV and the NASA aircraft involved in the SUCCESS
program.

    b. No.

5.  Date of arrival at ARM Southern Great Plains CART site: About 8 April.

6.  Dates of operation: About 10 April- 10 May

7.  Hours of operation: Various, but probably mostly during afternoon
aircraft missions.

8.  Date of departure: About 10 May

9.  Names of personnel who will be working at the site:  Kenneth Sassen and
Ching-yu Hsueh (lidar operators), Tehan Chen (radar operator), James
Campbell and Jennifer Barnett (visiting graduate students).

10. Requested instrument location: Collocated with our truck containing the
PDL system

11. Site Support

       a. No (see b).

       b. Yes. A forklift (or several hands) to unload and load the radar
equipment from the truck to its sheltered location.

       c. No.

       d. Yes (if not collocated with the PDL)- Voice only.

12. Facility Requests

       a. The unit is comprised of a self-contained 3'x3'x5' computer
station and a 5'-high transmitter topped by a 3'-diameter dish, which is
mounted on a wheeled platform to move the transmitter out of shelter to
collect data.

       b. None.

       c.  A flat porch accessed through a 3'-wide door, or garage door.

       d.  Vehicle and operator access whenever the unit is in use.

       e.  Radar plus computer station require shelter.  Also require a
storage area for empty shipping boxes.

13. Equipment Requested

       a. None.

14. Expendables Requested

        None

15. Utilities Requested

       a. Power: About 35 amps peak at 110 V, using standard 3-pronged plugs.

       b. No.

       c. No.

16. Interference and susceptibility to Interference (include
    information on power output and frequency

        Weak electromagnetic interference is possible for/from other radar
operating at the same frequency.

17. Safety Issues

       a. Yes: output of about 1.2 KW, dish should not be looked into at
close range.

       b. No.

       c.  No.

       d. None.

       e. None.

       f.  No.

       g. Will safety equipment be properly maintained and
          deployed (yes, no, or n/a)?

            (1) Fire Extinguishers: Yes.

            (2) Signs Denoting
        High Voltage
        Micrwave Radiation

        h. No.

18. Do you have weather support requirements?

        a. Weather forecast support for operations
        Provided in connection with UAV and SUCCESS operations.

        b. Weather warning support requirements
        We do not operate during inclement or severe weather.

19. None.
