1.1 Product overview

According to International Standard ISO 9060:1990 and the World Meteorological Organisation (WMO) a pyranometer is the

designated type of instrument for the measurement of hemispherical (global or diuse) solar radiation integrated over the

wavelength range from 0.3 to 3 m (300 to 3000 nm). All pyranometers within the CMP series are compliant with one of the

classes speciﬁed by the international standard.

The albedo of a surface is the extent to which it diusely reﬂects short-wave radiation from the sun in the wavelength range from

300 to 3000 nm. It is the ratio of the reﬂected radiation to the incoming radiation and varies from 0 (dark) to 1 (bright). As an

indication, albedo is about 0.15 for grass, 0.5 for dry sand and 0.8 for fresh snow.

CMA series albedometers consist of two pyranometers. The upper measures incoming global solar radiation and the lower

measures solar radiation reﬂected from the surface below. When the two signal outputs have been converted to irradiance in W/m²,

the albedo can be simply calculated.

This manual, together with the instruction sheets, provide information related to the installation, maintenance, calibration,

product speciﬁcations and applications of the CMP series pyranometers and CMA series albedometers.

1.1.1 The pyranometer and albedometer

The CMP series instruments are high quality radiometers designed for measuring short-wave irradiance on a plane surface

(radiant ﬂux, W/m²) which results from the sum of the direct solar radiation and the diuse sky radiation incident from the

hemisphere above the instrument. The CMA series also measures the amount of the incoming radiation which is reﬂected by the

surface below.

There are six models in the CMP series; CMP 3, CMP 6, CMP10, CMP 11, CMP 21 and CMP 22; and two models in the CMA series,

CMA 6 and CMA 11.

To achieve the required spectral and directional characteristics CMP series pyranometers and CMA series albedometers use

thermopile detectors and glass domes. They have built-in bubble levels and the pyranometers have adjustable levelling feet.

Snap-on sun shields reduce solar heating of the housings. Albedometers have a mounting rod ﬁtted and an integral glare-

shield to prevent direct sunlight from below the horizon entering the lower pyranometer. The waterproof connectors have

gold-plated contacts.

The instruments are normally delivered with a waterproof plug pre-wired to a high quality signal cable, typically this is 10 m

long but other lengths are available. The instruments can also be ordered with a plug only, for the user to ﬁt their own cable.

CMP pyranometers and CMA albedometers do not require power to operate. Radiation falling onto the sensing element produces

a small analogue output voltage.

CMP 3 is smaller and lighter than the other CMP series pyranometers. It features a 64-junction thermopile sensing element with

a highly absorptive and spectrally ﬂat black coating to capture incoming radiation and convert it to an electrical signal. This

detector is protected by a high quality glass dome which is 4 mm thick. The housing is completely sealed.

CMP 6 uses the same sensing element as CMP 3 but has improved performance due to the double glass dome construction and the

increased thermal mass of the larger housing. The glass used has better transmission of ultraviolet radiation than the CMP 3 glass.

The two high quality concentric domes, 2 mm thick, reduce directional error and improve thermal isolation. The radiometric

levelling is more accurate and CMP 6 has a drying cartridge with replaceable desiccant.

CMP10 and CMP 11 have a 32-junction thermopile sensing element which features faster response, better linearity and a wider

measurement range than the CMP 3 and CMP 6. CMP10 and CMP 11 have built-in temperature compensation. The CMP10 has

internal desiccant that lasts for 10 years and the CMP 11 has a removable drying cartridge.

CMP 21 is similar to the CMP 11 but has individually optimised temperature compensation and a sensor is ﬁtted to monitor the

housing temperature. Each instrument is supplied with its own temperature and directional response for post-processing of

recorded data by the user. A Pt-100 temperature sensor can be ordered instead of the standard 10 kΩ thermistor.

CMP 22 has all the features of CMP 21 but uses two 4 mm thick very high quality quartz domes for a wider spectral range and reduced

thermal osets. Because of the high optical quality and refractive index of these domes the directional error is greatly reduced.

CMA 6 is an albedometer comprised of two CMP 6 sensing element and dome assemblies in a single housing with two signal

outputs on one signal connector.

CMA 11 uses two of the same sensing elements as ﬁtted to the CMP 11 pyranometer, for similarly improved performance over the CMA 6.

Features and speciﬁcations of the CMP and CMA instruments are explained later in this manual.

1.1.2 International Standards

CMP 3 exceeds the requirements of ISO 9060:1990 for a Second Class Pyranometer.

CMP 6 and CMA 6 are fully compliant with the requirements of ISO 9060:1990 for a First Class Pyranometer.

CMP10, CMP 11 and CMA 11 are fully compliant with the requirements of ISO 9060:1990 for a Secondary Standard Pyranometer.

CMP 21 and CMP 22 signiﬁcantly exceed the requirements of ISO 9060:1990 for a Secondary Standard Pyranometer.

CMP series pyranometers and CMA series albedometers are calibrated in accordance with Annex A.3 of ISO 9847 ‘Calibration of

Field Pyranometers by Comparison to a Reference Pyranometer’. Annex A.3 refers to ‘Calibration Devices Using Artiﬁcial Sources’.

Calibrations are traceable to the World Radiometric Reference (WRR) in Davos, Switzerland.

CMP series pyranometers comply with IEC 60904-1 ‘Photovoltaic devices - Part 1: Measurement of Photovoltaic Current-Voltage

Characteristics’.
