Quantifying the Great American Solar Eclipse 2017

During the Great American Solar Eclipse of 2017, Dr. Bruce Bugbee, president of Apogee Instruments and a professor at Utah State University, deployed a suite of sensors in the path of totality in Rexburg, Idaho to measure various environmental parameters during the eclipse. In this video, Bruce discusses his findings. The Apogee sensors he used included spectroradiometers, a net radiometer, pyranometers, full-spectrum quantum sensors, infrared radiometers, and a precision thermistor inside an aspirated radiation shield.

Apogee Quantifies the Solar Eclipse

Apogee will be on site quantifying the Great American Solar Eclipse from the center of the path of totality on August 21, 2017. As one of the biggest solar radiation events of the century, Dr. Bruce Bugbee and NYU Professor, Dr. Tyler Volk, will be manning a full suite of Apogee radiation sensors including spectroradiometers, a net radiometer, pyranometers, quantum sensors, infrared radiometers, and a precision thermistor inside an aspirated radiation shield while in Rexburg, Idaho. Stay tuned for a full report and video of their results.

Weather Information Service Engine Project (WISE)

Weather Information Service Engine Project (WISE) is dedicated to resolve urban environmental issues including high-resolution weather forecasting, urban flooding prediction, road meteorology and urban carbon dynamics, and new urban service systems to minimize and mitigate the impacts of natural disasters and climate change on urban dwellers. WISE is targeting South Korea’s capitol, the megacity Seoul, and surrounding urban areas. Recently they started a project called the City Energy Monitoring System, focused on researching greenhouse gas emission from cars, buildings, and the people in Seoul City. As part of the project they are trying to analyze how concrete buildings, houses, and asphalt roads in the city interact with nature, such as rivers and parks that are in and surround the city. One of seven weather stations installed by B&P international for WISE project City Energy Monitoring System. To fill this study B&P International installed seven weather stations throughout Seoul city. Six of the weather stations were installed on building roof tops, while the final station was installed in a rural area near Seoul. The stations are being used to monitor air temperature, humidity, wind, net radiation, CO2/H2O concentration etc. as well as building surface temperature. Building surface temperature is being measured with Apogee SI-111 Infrared Radiometers, temperature probes, and infra-red cameras. SI-111 Infrared Radiometer monitors building surface temperature. Data collected from the temperature probe and the SI-111 at the same site are being compared and analyzed. The SI-111 is being used as the standard for accuracy, as measurements from the temperature probe may be heated by solar radiation. As the data is collected, it is transmitted to a computer at the WISE office using 4G LTE modems. From there the data is uploaded to the WISE website, where it can be viewed in real time for analysis. More information on WISE >

Monitoring PV Panels on Jin Jeop Library

Two Apogee Instruments SP-110 Silicon-cell Pyranometers have been integrated by Daeyeon CNI as part of a PV monitoring system at the Jin Jeop library located in Namyangju city, Gyunggido, Korea. The library has a PV power generation facility on the roof of the building that is converting DC voltage to AC voltage and suppling power to the building for electric lamps, air conditioning, and water heaters. Jin Jeop Library in Namyangju City, Gyunggido, Korea The two SP-110 pyranometers are mounted to the side of the PV panels. One pyranometer is mounted horizontal to measure the global solar irradiance, and the other is mounted tilted in the plane-of-array to measure global tilted irradiance or plane-of-array irradiance. Although the pyranometer measuring plane-of-array irradiance is mounted at the same angle as the PV panels and is measuring the irradiance the panels are receiving, both pyranometers are being used to monitor the system. Top pyranometer is measuring plane-of-array irradiance. Bottom pyranometer is measuring global horizontal irradiance. The data from the SP-110 sensors allow the integrator to see when irradiance measurements for the PV panels are below the accepted threshold to maintain the PV system. They are then able to use the data from the pyranometers and other instruments that are providing panel temperature, current, and voltage data to investigate the system and fix or replace bad electronic parts and PV panels. Apogee Instruments SP-110 Silicon-cell Pyranometers collect global horizontal irradiance and plane-of-array data to monitor the PV system at Jin Jeop Library in Korea.

High Throughput Field Phenotyping Multi-sensor System

Apogee Instruments' SI-131 Infrared Radiometer (referred to in reference as thermal infrared radiometer, TIR) was selected to be part of a multi-sensor high throughput field phenotyping system for soybean and wheat breeding. The infrared radiometer was used to collect canopy temperature, one of six crop canopy sensor based traits being studied. Temperature, along with the remaining five sensor based traits: canopy height, two NDVI indices, reflectance, and RGB were studied to find a correlation with final yield. Field phenotyping system platform featuring Apogee Instruments' infrared radiometer. The system consisted of a manually operated platform using a laptop with a special developed LabVIEW program as a controlling unit to collect, synchronize, and store measurements from all sensors for analysis. Apogee's SI-131 was mounted to a sensor bar on the platform at a distance that allowed for a representative subarea of the crop canopy to be seen in the sensor's field of view. The analog infrared radiometer was connected to the laptop through a USB data acquisition board. The LabVIEW program read the infrared radiometer outputs from the analog input ports and applied Apogee's calibration equation to convert the sensor voltage to degrees Celsius. Yufeng Ge, a Biological Systems Engineer from the study said, "The infrared radiometer by Apogee Instruments is among one of the most reliable and trustworthy sensors I have used." Sensors that were mounted to the sensor bar of the platform. The system was successfully tested over 240 plots of wheat and 120 plots of soybean crop using a manual stop-measure-go data collection method.* The study determined that final grain yield of soybean is strongly correlated with all six sensor base traits, and suggested the usefulness of the sensor system in plant breeding. Read the Full Article > *A stop-measure-go data collection method was used because slow response times from sensors did not allow for continuous measurement (the SI-131 with a response time of 0.6 seconds was noted as one of these sensors in the reference article). Since this study took place Apogee has developed  high speed, analog infrared radiometers with a response time of 0.2 seconds and SDI-12 infrared radiometers...more information >

Reflectance Measurements in Cotton Fields

Dr. Glen Ritchie of the University of Georgia has used model PS-100 spectroradiometer to take reflectance measurements in cotton fields and estimate defoliation. Chlorophyll gives plant leaves a reflectance spectrum characteristically different from that of soil. Reflectance measurements can be reported in µmol m-2 s-1, W m-2, or as a relative value. View poster presented at ASA meeting.

Irrigation Study

Dr. Joan Girona of the Institute of Agroalimentary Research and Technology in Catalonia, Spain, is studying irrigation and the water and nutrient needs of fruit trees. He needed to capture pyranometer readings throughout his orchard. Dr. Girona mounted Apogee pyranometer sensors and Campbell Scientific dataloggers on a carefully laid out model train track around the orchard. The train carrying the pyranometer sensors and dataloggers wound around the track and could take measurements at specified intervals. Dr. Girona could then take thousands of measurements. His system was so effective he plans to continue running it for more experiments in the future. Learn more about Dr. Girona’s experiment by reading the original article on Campbell Scientifics’ website.
