Abstract

The PRIMET Horizontal Radiation Shield Comparison (PHRSC) experiment compares the difference between the air temperature measurements of a reference temperature sensor inside a fan aspirated radiation shield and temperature sensors located inside passively aspirated radiation shields including a cotton region shelter, Gill multi-plate shield, and a custom-fabricated model. Observed variables include air temperature, wind speed, and incoming and reflected solar radiation. Data was collected in the field between 2010 and 2017 at the Primary Meteorological Station (PRIMET) at H.J. Andrews Experimental Forest, located in Oregon’s Western Cascades (44.21, -122.26, elevation 430m).

Purpose
  • To examine the measurement differences between air temperature instruments that are using the same sensor but different radiation shields. These measurement differences are examined for various temperature statistics (average, minimum, maximum) at varying temporal resolutions. This information will help researchers understand the magnitude of measurement bias associated with instruments that have been used to record air temperature at H.J. Andrews meteorological stations over time. This bias can have implications during analysis when air temperature data from different instruments is combined into one dataset without accounting for differences between air temperature methods.

Abstract
  • The H.J. Andrews Experimental Forest is a living laboratory that provides unparalleled opportunities for the study of forest and stream ecosystems in the central Cascade Range of Oregon. Since 1980, as a part of the National Science Foundation Long Term Ecological Research (NSF-LTER) program, the Andrews Experimental Forest has become a leader in the analysis of forest and stream ecosystem dynamics.
  • Long-term field experiments and measurement programs have focused on climate dynamics, streamflow, water quality, and vegetation succession. Currently researchers are working to develop concepts and tools needed to predict effects of natural disturbance, land use, and climate change on ecosystem structure, function, and species composition.
  • The Andrews Experimental Forest is administered cooperatively by the USDA Forest Service Pacific Northwest Research Station, Oregon State University and the Willamette National Forest. Funding for the research program comes from the National Science Foundation (NSF), US Forest Service Pacific Northwest Research Station, Oregon State University, and other sources.

Study Area Description
  • Long-Term Ecological Research
    The Andrews Forest is situated in the western Cascade Range of Oregon, and covers the entire 15,800-acre (6400-ha) drainage basin of Lookout Creek. Elevation ranges from 1350 to 5340 feet (410 to 1630 m). Broadly representative of the rugged mountainous landscape of the Pacific Northwest, the Andrews Forest contains excellent examples of the region's conifer forests and associated wildlife and stream ecosystems. These forests are among the tallest and most productive in the world, with tree heights of often greater than 250 ft (75 m). Streams are steep, cold and clean, providing habitat for numerous aquatic organisms.

No method step description paragraphs listed.

Instrumentation:

  • <para>Four air temperature instruments all used the same Campbell Scientific 107 thermistor sensor (Sensor accuracy: +/-0.2 deg C between 0 and 60; +/-0.4 deg C below 0 to -35) and four different radiation shields: </para> <para>1) fan-aspirated (ASP or aspirated) - R.M. Young 43502-L compact aspirated shield (shield radiation error <0.2 deg C @ 1000 W/m2) </para> <para>2) cotton region shelter (CRS) - NovaLynx 380-605 large instrument shelter (no accuracy information available) </para> <para>3) Gill multi-plate (Gill) - R.M. Young 41303-5A 6-plate solar radiation shield (no accuracy information available) </para> <para>4) a custom-fabricated shield developed by staff at the research site (HJA) - 8-inch long, 3.5 inch diameter, schedule 40 PVC pipe split in half lengthwise over PVC tubing containing sensor (no accuracy information available) </para> <para>One propeller anemometer was used to measure wind speed - R.M. Young 05103 (Resolution: 1.0 m/s ; accuracy: +/-0.3 m/s or 1% of reading) </para> <para>One upward-facing pyranometer measured incoming solar radiation (ISR), and one down-facing pyranometer measured reflected solar radiation – both CM3 Kipp & Zonen (Response time: 18s; spectral range 305-2800 nm; sensitivity: 10-35 micro V/W/m2; error: +/-25 W/m2) </para> <para>All sensors were connected to the same data logger - Campbell Scientific CR1000 </para> <para>None of the instruments were calibrated during the course of the study. </para>
Quality Assurance - MS048
  • Air temperature, incoming and reflected solar radiation, and wind speed data were collected continuously between July 2010 and April 2017. Measurements were taken every 15 seconds, and the average for a 15-minute period (60 observations) was recorded (referred to hereafter as “15-minute average observations”). Additionally, from April 2015 to April 2017, measurements were taken every 15 seconds, and for each 5-minute period (20 observations), the maximum and minimum air temperature and maximum incoming and reflected solar radiation and wind speed were recorded (referred to hereafter as “5-minute observations” with the relevant statistic specified).
  • All data were reviewed for quality control using an automated process (GCE Data Toolbox Version 3.9.4b - https://gce-lter.marsci.uga.edu/public/im/tools/data_toolbox.htm). Rows with missing observations for aspirated air temperature, incoming solar radiation, reflected solar radiation, or wind speed were removed, with a total of 6,097 rows (out of 210,504) removed from the 15-minute data and 8,358 rows (out of 210,792) removed from the 5-minute data. Data logger issues from February 27-March 7, 2013 and August 2-31 in 2016 caused most missing values.

Sampling

Study Extent
  • The study was located at the Primary Meteorological Station (PRIMET) at H.J. Andrews Experimental Forest, located in Oregon’s Western Cascades (44.21, -122.26, elevation 430m). PRIMET is sited in a relatively flat clearing approximately 29 x 23 m2 in size, with conifer forests outside the perimeter. It is located in the bottom of a valley with steep ridges to the southeast and northwest. Annual precipitation averages 2200 mm and occurs primarily November through May. Snow can accumulate at this site in winter, but it does not remain for long periods. Summers are generally dry and warm, with cool nights and occasional thunderstorms.
  • Sampling frequency: 15 and 5 minute
Sampling Description
  • Instruments measuring air temperature, wind speed, incoming solar radiation and reflected solar radiation were placed side-by-side at 1.5m above the ground. There were four air temperature instruments, all using an identical sensor (Campbell Scientific 107 thermistor) but different radiation shields: 1) fan-aspirated (ASP or aspirated), 2) cotton region shelter (CRS), 3) Gill multi-plate (Gill), and 4) a custom-fabricated shield developed by staff at the research site (HJA). One propeller anemometer was used to measure wind speed. One upward-facing pyranometer measured incoming solar radiation (ISR), and one down-facing pyranometer measured reflected solar radiation (RSR). All sensors were connected to the same Campbell Scientific CR1000 data logger.
