Meet Danny and His Aquarium Blog Danny "Daniel and the Lights Den" Larsen

Meet Apogee's newest addition to the marketing team Danny Larsen. Danny started at Apogee this spring helping with international business and technical support. He is also an aquarium hobbyist and is excited to set up an aquarium at Apogee Instruments headquarters. Danny is looking forward to learning more about using our sensors to setup and maintain an aquarium and will be using the aquarium to test Apogee's quantum sensors. You can follow Danny's blog Danny "Daniel and the Lights Den" Larsen for updates on the aquarium and his ocean adventures.

Danny Larsen Bio
I graduated from one of the best schools in the world, Utah State University. I graduated with a degree in International Business from the Jon M. Huntsman School of Business. I always loved business, and had the opportunity there to travel around Asia. I found out about Apogee, and I had to join them as their International Business and Technical Support Specialist. Apogee sells sensors that help the environment and sensors for measuring the light that keeps plants and corals alive.

Apogee's first saltwater tank.

I come from a second generation of diving. My mom being the first to start diving. There I learned a love for the ocean. Living in Utah, there aren’t a lot of options for diving, so I’ve done a lot of traveling. I’ve been able to dive with manta rays, icebergs, Great White Sharks, and see a geothermal chimney teaming with life. 

Wife mad at me for a fish giving me a smooch.

I can’t wait to get my kids diving. As the saying goes, a family that dives together, thrives together.

Son wanting to play with daddy after a dive.

Coolest diving in the world, plus iceberg ice is the only way to cool down your Mountain Dew.

After time, the call of the ocean becomes strong. That’s why I started my first aquarium in 2010. I used a sea anemone that told me where the good light and current was at and would put my other corals. Apogee takes the guess work out of where the best lighting for the corals is at. It made my life a lot better, and was able to maintain beautiful aquariums.

Found the Titanic, or the Saganaga, in Newfoundland, Canada.

Diving with a Great White Shark.

When I’m not diving, working for the best company in the world, or tinkering with the aquariums, I love to bike, rock climb, and hike. I’m also a fan of fantasy novels, and have a husky and chameleon at home, and think the only way of roasting marshmallows is over lava. 

It really is the best way to roast a marshmallow, how would a steak taste?

Apogee Visits Asia

In June, key representatives from Apogee paid a long-overdue visit to a few of our partners in China, South Korea, and Japan. Apogee has a long history of selling sensors in Asia, and we were excited to visit our representatives for the first time in their homeland. Dr. Bruce Bugbee, Mark Blonquist, and Devin Overly soon discovered that we should’ve visited a long time ago, as our partners gave great insights and showed wonderful hospitality.

In China, they visited Campbell Scientific Beijing, Beijing Techno Solutions, Channel Technology, Dianjiang Technology, and Truwel Scientific in a series of very productive training and strategy sessions. From the visit, they learned that Apogee’s infrared radiometers are particularly popular in China for use on flux towers.

The last leg of the trip was to Tokyo, Japan, where the team met with Fujiwara, Climatec, Senecom, and EKO. They were treated extremely well and learned many things about the Japanese market. In particular, Apogee’s quantum sensors are very popular in Japan due to the advanced level of research in horticulture and agriculture.

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.

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.

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.

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.

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.

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."

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.

*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.

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.
