Press Release:
SPECTRAL EVOLUTION provides portable spectroradiometers that can take albedo measurements in the field.

Haverhill, MA – September 1, 2020 – SPECTRAL EVOLUTION provides portable spectroradiometers that can be used to take albedo measurements in the fieldMeasuring Albedo. Spectroradiometers include the SR-6500, RS-8800, RS-5400, PSR+™, RS-3500 and PSR-1100f. These spectroradiometers and FOV lenses are calibrated to NIST standards for absolute radiance measurements. Using a calibrated straight or right angle diffuser, a spectra of the downwelling irradiance can be accurately measured.

Albedo is a measurement of the electromagnetic solar radiation reflected by the earth’s surface divided by the radiation incident on its surface. It is a fraction of the incident sunlight that a surface reflects. Albedo has a value from zero to one, with zero being a black totally absorbing surface and one being a mirror-like completely reflecting surface. Bright earth albedos like snow, clouds and ice have albedos ranging from 50% to 90% while dark surfaces such as asphalt roads, dark soils and forests have albedos ranging from 5% to 20%.

All our portable spectroradiometers have the following features:
• Wide range of accessories including direct attach lenses, FOV lenses, contact
probes, pistol grip and unique leaf clip
• Auto-shutter, auto-exposure and auto dark correction
• Rugged design with no moving optical parts for field use
• Optional rugged tablet with digital camera, voice note recording, GPS and more.
• DARWin™ SP Data Acquisition software stores all scans and associated data as
ASCII files for use with other third party programs, like ENVI or chemometrics
software such as Unscrambler from Camo Analytics
