USING APOGEE NET RADIOMETERS WITH ZENTRA SYSTEM
1. INTRODUCTION
The Apogee Instruments SN-500 Net Radiometer is a four-component net radiometer
designed for continuous measurement of net radiation in outdoor environments. The
net radiometer uses four filtered blackbody thermopile sensors to measure the four
components of net radiation independently. An upward-facing pyranometer and pyrgeometer
pair measures the downwelling shortwave and longwave radiation, respectively, while a
downward-facing pyranometer and pyrgeometer pair measures upwelling shortwave and
longwave radiation. The four radiation components can be used individually or combined
to yield several important parameters including net radiation, which is a key variable in the
surface energy balance, shortwave irradiance, net short- and longwave radiation, albedo, and
many others.
The information in this document explains how to install the required hardware to mount the
Apogee Net Radiometer that has been preconfigured by METER Group to work seamlessly
with METER ZENTRA series data loggers. Details of how the ZENTRA system handles the
data are also included. Please read this document carefully in its entirety before going out to
the field.
