How our remote sensing technologies work
The heart of Radiometrics’ thermodynamic profilers are incredibly sensitive microwave radiometers that passively measure Planck radiation – electromagnetic energy radiated by all substances. These measurements (coupled with ground meteorology and climatological data) are used to produce continuous profiles of atmospheric temperature, relative humidity, vapor, and liquid water, measure soil and snow-pack moisture, and even remotely measure sea surface salinity.
RAPTOR Radar Wind Profilers (RWP) transmit short pulses of electromagnetic energy skyward, and measure the signals reflected from atmospheric turbulence –the same small density discontinuities that cause stars to twinkle. The signal strength, phase, and timing all provide information that our signal processing software uses to determine profiles of wind speed and direction. Depending on the transmitter frequency, power, and antenna size, RWP systems can measure wind profiles to the top of the surface boundary layer or into the stratosphere.
Sodars transmit short audio frequency pulses, and measure the doppler shift of the reflected signals. Digital signal processing software uses the reflected signal strength, timing, and Doppler shift to produce high-resolution wind profiles in the lower boundary layer. Depending on the Sodar model, winds can be measured up to a few km above ground level.
