Case Studies

Aspirated Radiation Shield
Tasmania: Ecological Research
Eight TS-100 shields used to provide air temperature measurements to monitor long-term ecological health dynamics within wet eucalyptus forest at the Warra long-term ecological research site (LTER).
TS-100 at Utah State University
The USU weather station uses both an aspirated and static shield to monitor air temperature. A real-time graph on the site shows errors that occur when using static shields.
TS-100 at Peter Sinks
TS-100 used on a weather station at a record-setting cold location-Peter Sinks, Utah.
Infrared Radiometers
High Throughput Field Phenotyping Multi-sensor System
Infrared radiometer measures canopy temperature on a multi-sensor system for high throughput field phenotyping in soybean and wheat breeding.
Weather Information Service Engine Project (WISE)
SI-111 Infrared Radiometers measure building surface temperature as part of Weather Information Service Engine (WISE) Project.
Temperature Free-Air Controlled Enhancement T-FACE
Simulating warmer conditions by applying a heat treatment to open-field plant canopies. Infrared radiometers provide the data and control the heated plot temperatures.
Measuring ground surface temperature to measure snow runoff.
Forecasting Ice Formations
Forecasting ice formation on road surfaces using infrared radiometers on a mobile system.
Colombia Rose Fungus Study
Studying conditions that cause fungus growth on roses.
Crop Water Stress Index
Using infrared radiometers to determine water schedule for plants.
Oklahoma Mesonet
Measuring the temperature of the interface between the earth's surface and its atmosphere on automated meteorological networks spaced evenly across Oklahoma.
Oxygen Sensors
Soil Oxygen Concentration
Quasi-continuous measurements of bulk soil oxygen concentration in managed and natural ecosystems.
Google's Project Loon
Apogee's SP-230 heated pyranometer was selected to monitor PV panels on Project Loon.
Monitoring PV Panels on Jin Jeop Library
SP-110's are integrated as part of a PV monitoring sytem for a PV power generation facility on the roof of the Jin Jeop library in Korea.
Solar Power Plants on Lakes and Dams
Studying solar radiation at different angles to determine locations for solar power plants.
Irrigation Study
Pyranometer mounted on model train to collect measurements in orchard for irrigation study.
Quantum Sensors
PAR Measurements Characterize Tree Coverages
Using line quantum meter to study the percent of PAR (under canopy/open sky) and its relation to survival and initial growth of native forest species.
Controlling Flowering of Orchids in Greenhouse
Line quantum sensor used to measure PPFD and daily light integral, while experimenting with temperature to control flowering.
Reflectance Measurements in Cotton Fields
Estimating defoliation of cotton using reflectance data.
