Solar Calendars, are available from January 1999 to the present month.
Objectives
Provide accurate and continuous 1-minute measurements of
Direct,
Diffuse, and
Global
solar irradiances for the Baseline Surface Radiation Network.
Serve as an independent measurement platform to provide redundant
measurements of key shortwave irradiance elements for the Baseline
Measurement System (BMS) also in continuous operation at the Solar
Radiation Research Laboratory (SRRL).
Approach
A separate radiometer mounting platform, developed and tested at SRRL
for deployment in Saudi Arabia, is used to position the instruments.
Thermopile-type radiometers are used to collect the following irradiance elements:
Direct-Normal -- EPLAB Model NIP mounted in ST-1 solar tracker
Diffuse Horizontal -- EPLAB Model PSP mounted in TD tracking disc shade device.
Global Horizontal -- EPLAB Model PSP
Data acquisition by a Campbell Scientific, Inc., model CR10X data logger
programmed to output 1-minute averages of 2-second samples of each input
channel.
Data checked for quality using automated system based on SERI_QC.
