Description

These data are published in Hirsh et al., see related publications section.

Methods & Sampling

Surface irradiance measured from June to October 2018. Weather station located on the roof of the Monterey Bay Aquarium (36.62 °N, 121.90°W), approximately 310 m from the kelp mooring site. Eric Kingsley provided weather station data from the Monterey Bay Aquarium

Total solar radiation (surface irradiance) was measured by an Eppley Model Precision Spectral Pyranometer (PSP), at 2-minute intervals.

Data Processing Description

Raw data, no processing.

BCO-DMO processing notes:

Converted Timestap to ISO format, and timezone from Pacific Standard Time (PST) to UTC
Added latitude and longitude of sampling location

Precision Spectral Pyranometer

Supplied Name: Eppley Model Precision Spectral Pyranometer

Supplied Description:

Total solar radiation (surface irradiance) was measured by an Eppley Model Precision
Spectral Pyranometer (PSP), at 2-minute intervals.

Instrument Type

Generic Name: Precision Spectral Pyranometer

Acronym: Eppley PSP

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/112/

Generic Description:

This radiometer measures sun and sky irradiance in the range of wavelengths 0.285 to 2.8 microns, including most of the solar spectrum. The PSP is intended to weight the energy flux in all wavelengths equally. It is a "hemispheric receiver" intended to approximate the
cosine response for oblique rays. The Eppley Precision Spectral Pyranometer (PSP) is primarily used where high accuracy is required or where it is used to calibrate other pyranometers. The PSP outputs a low level voltage ranging from 0 to a maximum of about 12mV depending on sensor calibration and radiation level. An instruction manual provided by Eppley contains the sensor calibration constant and serial number. The Precision Spectral Pyranometer is a World Meteorological Organization First Class Radiometer and comes with a calibration certificate traceable to the World Radiation Reference and a temperature compensation curve. More information is available from Eppley Labs.
