NCAR/ATD/RTF Deployment for DASH04

(DAta confirmation of Solar telescope for HAO)

Introduction

This document describes the operation and measurements of the Integrated Surface Flux Facility (ISFF) and ATD SODAR during the scintillometer test for the Advanced Technology Solar Telescope (ATST) at the Boulder Atmospheric Observatory (BAO) near Erie, Colorado in January, 2004.

Schedule

Jan 5, 2004: Set-up
Jan 8, 2004: Full sodar operations start
Jan 9, 2004: Full tower operations start
Jan 31, 2004: Tear-down

Measurement Site

ISFF will instrument several levels of the NOAA BAO tower. For a complete description of this tower, see here.

Our GPS readings of position are:

Tower Latitude Longitude Altitude

300m 40deg 03'00.0" = 40.050deg 105deg 00'13.7" = 105.004deg W 1577m

5m 40deg 03'00.2" = 40.050deg 105deg 00'17.8" = 105.005deg W 1569m (probably not correct)

Tower	Latitude	Longitude	Altitude
300m	40deg 03'00.0" = 40.050deg	105deg 00'13.7" = 105.004deg W	1577m
5m	40deg 03'00.2" = 40.050deg	105deg 00'17.8" = 105.005deg W	1569m (probably not correct)

Instrumentation

Layout of ISFF sensors on the BAO and a small auxilliary tower. Sensors were at heights of 5, 10, 22, 50, and 100m.

Each of the instrumented levels had:

Sonic anemometer, Campbell CSAT3
Fast-response hygrometer, Campbell KH2O 30cm behind the CSAT3

In addition, at 5m:

Vaisala 50Y Humitter to measure air temperature and RH; in an NCAR aspirated radiation shield
Barometer, Vaisala PTB220B, with a single-disk static pressure port

for the measurement of state variables. T, RH, and wind speed and direction also are being measured by NOAA at 10, 50, and 100m.

The SODAR (a Metek DSDPA.90-24) was deployed at the outer tower guy point, approximately 260m South of the BAO tower. It will produce profiles of Cn^2_accoustic at as high spatial resolution as possible (5--10m).
