PAR Measurements Characterize Tree Coverages

The Center for Forest Research and Extension Andean Patagonian (CIEFAP) studies forest systems and land suitable for forestry in the Andean region of Patagonia Argentina. The center does research to contribute to sustainable development in the Patagonia region. Recently, CIEFAP has been studying the relationship between tree coverage and the survival and initial growth of native Andean-Patagonian forest species. The study is determining the % of PAR (under canopy/open sky) differing health of species are receiving to determine the % of PAR related to survival and initial growth. To do this study CIEFAP measured under canopy PAR using an Apogee MQ-301 line quantum sensor and open sky PAR using a ceptometer at different sites and times of day.   The results are still being evaluated, however, at this point CIEFAP has been able to determine that species receiving 50 to 60 % open sky PAR have the best survival and initial growth. Once the study is concluded CIEFAP will be able to use its data to make recommendations for the restoration of degraded forests.

Solar Power on Lakes and Dams

Korea Water Resource Corporation (K-water) is the number one clean energy producer in Korea. The company operates several clean energy plants including hydropower, tidal power, wind power, and solar photovoltaic power. More recently K-water developed the world’s first ecofriendly floating solar photovoltaic power system called SOLATUS, which was installed at Hapcheon Dam. The company plans to install additional floating photovoltaic power plants on dams and lakes in Korea by 2022. Part of the installation process is determining the best location for the power plant. To find these locations K-water is studying solar radiation at different angles, using a configuration of eight Apogee SP-110 Silicon-cell Pyranometers, and weather data, using wind, temperature, and humidity sensors.   Once K-water has collected all of the data from the sensors it will be reviewed to find the best location for the new power plants and the optimal angles for the solar panels to collect power throughout the day.

Peter Sinks

The TS-100 has been deployed for the past year on a weather station at a record-setting cold location in the contiguous United States - Peter Sinks, Utah. It is used to accurately measure the extremely cold air temperatures that occur at the site. The Peter Sinks site uses two yellow-bead thermistors and two PRTs in an Apogee TS-100 to make replicate measurements. Note the Apogee SP-230 all-season pyranometer in the picture as well. A webinar of the TS-100 with more information on the Peter Sinks site can be found here. The Peter Sinks information starts at approximately 15:25.
