Net Radiometers

Net Radiometers

– For the measurement of the energy balance 

Net Radiometers are used to measure incoming radiation from the sun and sky and outgoing radiation from the ground. Shortwave radiation of 0.3 to 3 µm wavelength reaches the earth’s surface, where some is reflected and the rest of the energy is absorbed by the surface. Incoming long-wave Far Infrared(FIR) radiation from 4.5 to more than 40 µm is also absorbed by the surface, which heats up and emits FIR back to the sky.

The main applications for net radiometers are in agro-meteorology, in particular for the study of evapo-transpiration; and in climatology, meteorology and hydrology for measurement of the radiation balance. Monitoring over glaciers and icefields is of particular interest to global warming studies. Net radiometers are often used in conjunction with a small automatic weather station.

Pyranometers

Pyranometers

– For the accurate measurement of solar irradiance –

Scientists,researchers and commercial companies in renewable energy, climatology, weather, agriculture, water resources and environment all require accurate and reliable measurements of solar radiation. The measurement is made by pyranometers, which are radiometers designed for measuring the total (global) irradiance on a plane surface resulting from radiant fluxes in the wavelength range from 300 to 3000 nanometers (nm).

Pyrgeometers

Pyrgeometers

– For the precise measurement of far infrared radiation –

Radiation from the sun is mainly in the ‘shortwave’ range from300 to 4000 nm (4µm) that includes the visible and ultraviolet. A proportion of this radiation is absorbed by clouds, aerosols and molecules in the atmosphere which warm up and radiate ‘long-wave’ radiation. This is far infrared thermal energy(FIR) at wavelengths from 4.5 µm to beyond 40 µm.

Both the short-wave and long-wave radiation reach the earth, where some is reflected and the remainder warms up the surface. The earth radiates long-wave thermal energy back to the sky. Short-wave radiation is measured by a pyranometer and long-wave radiation by a pyrgeometer.

Solar accessories

Solar accessories

Specially designed for solar instruments –

Most of our solar radiation instruments do not require external power and work out of the box, as delivered. They only need to be connected to a data logger in order to record the measured values. However, we produce a wide range of accessories to help with the installation and use of our solar radiometers.

Ventilation of radiometers improves the stability and quality of measurements and decreases the frequency of cleaning the domes. Our ventilation units also include heaters that can be externally switched on to clear frost and snow.

Several of our instruments, such as albedometers and net radiometers, are supplied with a mounting rod and others have a screw-in mounting rod available as an accessory. For instruments without these features we have mounting fixtures available which incorporate a plate and a rod. These fixtures can take a radiometer on one side only, facing upwards or downwards, or two radiometers (one on each side) to make a net radiation measurement. We also have a bracket available to enable easy attachment of a mounting rod to a pole or a wall.

Sun Trackers

Sun Trackers

– For solar tracking and PC-bases positioning operations –

Solar radiation is normally measured using a pyranometer that sees the whole hemisphere above it and responds to radiation from both sun and sky, the ‘global’ solar radiation. However, it is often necessary to accurately measure the ‘direct’ radiation coming only from the sun,particularly in solar energy, meteorology and climatology appplications.

A pyrheliometer has a view slightly larger than the sun and its aureole and does not see the rest of the sky. To make measurements it must point precisely at the sun and this is achieved using an automatic two-axis sun tracker. The sun tracker provides a stable mounting for the pyrheliometer and moves horizontally (azimuth) and vertically (zenith) to follow the solar arc.

Albedometers

Albedometers

– For global, net short-wave or albedo measurement –

The albedo of a surface is the extent to which it diffusely reflects short-wave radiation from the sun in the wavelength range from 300 to 3000 nanometers (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.

An Albedometer consists of two identical pyranometers that measure the incoming global solar radiation and the radiation reflected from the surface below. The two signal outputs are used to calculate the albedo and the net short-wave radiation.

Meteo tracking light

Meteo tracking light

Software geschikt voor het weergeven en opslaan van de windgegevens welke gemeten worden door de Mesa WNT windsensor.
In de software kan de actuele windstand middels een kompasroos (windrichting) of een schuifbalk (windsnelheid) worden afgelezen.
Via een instelbare interval worden de actuele windstand in een log-bestand opgeslagen. Iedere dag wordt automatisch een bestand gegenereerd met de windinformatie. Dit bestand kan met bv MS Excel worden geopend voor verdere analyse.

UV Radiometers.

The ultraviolet (UV) part of the solar spectrum has several beneficial effects for human biology, but too much can be very harmful. Therefore UV Radiometers can be used for solar ultraviolet radiation measurement.

Par Quantum Sensor – PQS 1

Exposure to light is essential for the growth of a plant. Under the influence of light from the sun, or from artificial sources, plants convert carbon dioxide and water into glucose and oxygen. This process is called photosynthesis. For the measurement of photosynthetically active radiation we advise the   Par Quantum Sensor – PQS 1.

Laboratory Thermopile.

There are many cases in laboratory environments, both in education and research where it is necessary to measure radiant fluxes with high accuracy. Typically this is an optical laboratory or a physics department where the equipment is mounted onto optical benches or tables. For this application a thermopile is the ideal type for the measurement of radiant fluxes in laboratory envirronments.

Atmosferische wetenschappelijke instrumenten
Pyrheliometers

Pyrheliometers

– For unattended normal incidence direct solar radiation measurement –

Solar rays travelling through our atmosphere are absorbed and scattered, resulting in different components of solar radiation reaching the earth’s surface. The direct component travels in a straight beam from the sun. Diffuse components come from all directions, due to atmospheric scattering processes.

A pyrheliometer is an instrument designed specifically to measure the direct beam solar irradiance with a field of view limited to 5°. This is achieved by the shape of the collimation tube, with precision apertures, and the detector design. The front aperture is fitted with a quartz window to protect the instrument and to act as a filter that passes solar radiation between 200nm amd 4000nm in wavelength.
