So much data! – Pick and choose what you want.
The SolarSIM-D2 is a hugely versatile device that can provide the function of a pyrheliometer, a spectroradiometer, a sun photometer and an ozone spectrophotometer, all in one. As a result the SolarSIM-D2 can provide an unparalleled quantity and quality of data – up to 14,000 data points per time stamp! Your SolarSIM-D2 can be configured to deliver any or all of the following:
Direct Normal Irradiance (DNI)
The SolarSIM-D2 provides an accurate measurement of the direct normal irradiance, under any sky conditions, over the complete 280-4000nm spectral range. The SolarSIM-D2 can also be configured to provide DNI over any custom spectral range.
Direct Spectral Irradiance
The SolarSIM-D2 resolves the direct solar spectral irradiance, under any sky conditions, over the complete spectral range of 280 – 4000nm, with 1nm resolution.
Aerosol Optical Depth
The SolarSIM-D2 provides aerosol optical depth values for each wavelength over the complete 280 – 4000nm range.
The SolarSIM-D2 resolves atmospheric ozone absorption values for each wavelength over the complete wavelength range, in addition to the total ozone layer thickness.
Precipitable Water Vapour
The SolarSIM-D2 resolves atmospheric precipitable water vapour values for each wavelength over the complete wavelength range, in addition to the total column amount.
The SolarSIM-D2 also provides accurate measurements of the ambient temperature and atmospheric pressure.
Intuitive and easy to use
The SolarSIM-D2 software features a windows-based GUI that provides user with easy visualization of all of the SolarSIM-D2’s data streams. Features include:
- Automatic SolarSIM detection.
- Visualisation of instantaneous spectral irradiance.
- Continuously updating daily plots of DNI, AOD, ozone, ambient temperature and pressure.
- Visualisation of raw optical channel outputs.
- Internal humidity monitor.
- Customised data acquisition rates for different data streams.
- Automated internal heater control.
By PC, data logger or over the internet – we’ve got you covered
The SolarSIM offers unparalleled connectivity options, suitable for any use case scenario.
With the SolarSIM Combox, users can get their SolarSIM-D2 operating straight out of the box via a direct connection to your PC or laptop.
Serial over Internet
The SolarSIM-D2 can be connected to a networked PC/server via a suitable serial-over-ethernet device.
The SolarSIM-D2 can be connected to RS485 capable dataloggers, via a free RS485 port. Spectrafy can provide the commands required for the data logger to request data from the SolarSIM-D2.
