The NASA STI Program Office ... in Profile

Since its founding, NASA has been dedicated to

the advancement of aeronautics and space

science. The NASA Scientific and Technical

Information (STI) Program Office plays a key

part in helping NASA maintain this important

role.

The NASA STI Program Office is operated by

Langley Research Center, the lead center for

NASA's scientific and technical information. The

NASA STI Program Office provides access to

the NASA STI Database, the largest collection of

aeronautical and space science STI in the world.

The Program Office is also NASA's institutional

mechanism for disseminating the results of its

research and development activities. These

results are published by NASA in the NASA STI

Report Series, which includes the following

report types:

• TECHNICAL PUBI,ICATION. Reports of

completed research or a major significant

phase of research that present the results of

NASA programs and include extensive data or

theoretical analysis. Includes compilations of

significant scientific and technical data and

information deemed to be of continuing

reference value. NASA',, counterpart of

peer-reviewed formal protk, ssional papers but

BOREAS TE-20 SSA Site Characteristics Data

Robert G. Knox

Summary

The BOREAS TE-20 team collected several data sets for use in developing and testing models of forest

ecosystem dynamics. This data set contains measurements of site characteristics conducted in the SSA

from 18-Jul-1994 to 30-Jul-1994. The data are stored in CSV files.

1. Data Set Overview

1.1 Data Set Identification

BOREAS TE-20 SSA Site Characteristics Data

1.2 Data Set Introduction

The Terrestrial Ecology (TE)-20 team studied site characteristics in the Southern Study Area (SSA)

of the boreal forest as part of the BOReal Ecosystem-Atmosphere Study (BOREAS) from 18-Jul-1994

to 30-Jul- 1994.

1.3 Objectives/Purpose

The objectives of the work were to:

• Provide data for developing and testing remote sensing algorithms for characterizing biomass

and surface cover in the SSA modeling subarea.

• Help place results from tower sites and auxiliary sites in context by sampling regional patterns

of structural and compositional variation; in conjunction with remote sensing, these will

facilitate scaling studies and surface flux modeling for aircraft flux data and taller tower sites

having larger and more heterogeneous flux surface areas.

Page 1
1.4 Summary of Parameters

The data parameters include site coordinates, species, diameter at breast height (DBH), tree height,

height to base of crown, surface cover, percent surface cover of subplots A and B, area, and site group

(Random sampling (RAN) or sampling for synthetic aperture radar (SAR) studies).

1.5 Discussion

From 18-Jul-1994 to 30-Jul-1994, investigators from TE-20 and Remote Sensing Science

(RSS)-15, with support from the Forest Ecosystem Dynamics (FED) and Shuttle Imaging Radar - C

(SIR-C) projects and TE-08, sampled an extensive series of sites in the SSA modeling subarea. Data

from these new field sites are intended to complement process studies and more intensive continuous

or multivisit data from regular auxiliary sites and tower sites. When combined with data from the

regular auxiliary sites, they will provide adequate sample size for developing and testing remote

sensing algorithms for characterizing biomass and surface cover in the SSA modeling subarea. They

will also help place results from tower sites and auxiliary sites in context by sampling regional patterns

of structural and compositional variation; in conjunction with remote sensing, these will facilitate

scaling studies and surface flux modeling for aircraft flux data and taller tower sites having larger and

more heterogeneous flux surface areas. Each site was sampled in a single visit, without extensive prior

screening. The data collected showed slowly varying soil and vegetation structural characteristics that

could be compared with imagery covering a wide timespan. In the same field effort, we also sampled

four sites of particular interest for SAR studies and four of the regular auxiliary sites for method

intercomparison, using the same field methods.

3. Theory of Measurements

4. Equipment

4.1 Instrument Description

Surveying wheel, fiberglass tapes, belt transects.

4.1.1 Collection Environment

Measurements were made in ambient outdoor conditions during the measurement dates.

4.1.2 Source/Platform

Measurements were taken from the ground.

4.1.3 Source/Platform Mission Objectives

The ground supported the trees and observers.

4.1.4 Key Variables

The variables include site coordinates, species, DBH, tree height, height to base of crown, surface

cover, percent surface cover of subplot A, percent surface cover of subplot B, area, and site group.

4.1.5 Principles of Operation

To assist in precise registration to high-resolution imagery, distances from easily recognized

landmarks were measured along roads with a surveying wheel. Most sites were reached by stopping at

fixed 2-kin intervals along major roads. Distances from road centers were measured with fiberglass

tapes and selected randomly between 150 and 250 m. The bearings selected were perpendicular to the

road (or its tangent line) and randomly assigned to either side. [Differential Global Positioning System

(GPS) reading for the landmarks selected would be widely useful for aircraft image registration.]

Similar randomization was used to reach exact site locations for the purposive sampling of four sites,

but with median distances from a starting point adjusted to fall within the stand of interest.

5. Data Acquisition Methods

Sites were sampled with five plots (see diagram below). The DBH was recorded for all trees within the

3.99-m radius plot whose DBH was at least 5 cm. Each tree was also assigned a species code and a

live crown position code. In 1- x 10-m belt transects, living woody stems 1-5 cm were counted, by

species and 1-cm diameter class. In two 1- x 1-m subplots, cover of vegetation less than 1 cm dbh and

of litter, open water, and bare soil was visually estimated using a 100-point 10- x 10-cm grid counting

technique. Cover percentages over 3% were rounded to the nearest 5%. Data from a site consist of 5

circular plots for trees, 5 belt transects for saplings and large shrubs, and 10 t- x 1-m surface cover

subplots. Circular plots were centered on the randomly selected location and on points 30 m N, E, S,

and W of that point. Belt transects were aligned to one side of the tape used to measure it to the center

point, for 5 m either side of the plot center. Surface cover subplots, A and B, were within the belt

transect, 2 to 3 m from the plot center. For each circular plot with sufficient live trees, two living trees

were randomly selected for height measurements and increment boring at breast height, totaling up to

10 trees per site with height, crown depth, and age information.

5-plot layout and 10 subplots sampled at each site.
