TAS Sensor Web: Middleton EQ16-E Pyrano-Albedometer solar sensor

Brief description

The Middleton EQ16-E Pyrano-Albedometer collects Solar data. The EQ08/16 User Guide provides a description of the instrument. Albedo is the ratio of upward to downward flux densities of solar radiation. The EQ16 Pyrano-Albedometer consists of a modified EQ08 Pyranometer with an additional inverted sensor assembly. The dual sensors are matched for response and sensitivity and their collector surfaces are parallel. The EQ16-E version is based on the EQ08-E and has dual in-built signal amplifiers. The data collected by these instruments is transmitted by Campbell loggers over the 3G mobile network, to a Hydro Tasmania FTP server. The logger is powered by solar panels and a rechargeable battery. The logger is scanning every three seconds and the Averages, Maximums and Minimums and Totalized values are for the log interval which is ten minutes (ie. 600s / 3s = 200 readings in 10 minutes). SolarDirect and SolarReflect are averaged. The data is subsequently retrieved from Hydro Tasmania via FTP and stored in a Postgres PostGIS database where it is made publicly available using a Sensor Observation Service that was created by 52 Degrees North. Recalibration of the instruments is carried out once a year by Hydro Tasmania personnel. Currently there is no automated Quality Assurance/Quality Correction process in place.
