Niwot Ridge: Carbon Dioxide Advection Study (NIWOT02)

Introduction

This document is a standard product of NCAR/ATD/RTF which gives an overview of the measurements taken using the Integrated Surface Flux Facility (ISFF) and conditions during the Niwot02 field experiment. This document can be obtained in hard copy from RTF upon request.

The ISFF portion of this study is being operated as an internal development program in support of the NCAR Biogeosciences Initiative, with some support from the NCAR Director's opportunity fund. ISFF is constructing two new instrument systems for this program:

Both systems will be deployed only within the forest canopy.

See the MMM WWW page for complete information about this program.

Location

At the CU Flux Facility within the CU Mountain Research Station, about 8? miles north of Nederland, Colorado. The fastest route from NCAR appears to be: (all distances approximate)

Chronology

The program is currently scheduled to run from 1 Aug - 15 Sept, 2002.

Measurement Sites

NCAR ISFF sensors are to be installed at three sites, roughly aligned with the existing USGS and CU towers:

Site Locations

(These are approximate, based on my handheld GPS which appears to have large errors.)
Site Station number Latitude (N) Longitude (W)
East 3 40° 2' 2.8" 105° 32' 44.9"
NCAR 2 40° 2' 2.2" 105° 32' 52.7"
West 1 40° 2' 0.5" 105° 32' 59.0"

Sensors

The layout of the sensors is shown here (and PostScript version).

The hydra system is described in a separate report.
