Infrared

Microwave

Combined IR and microwave method

Advantages

High level of self-radiation of the atmosphere

Aerosol does not affect the measurement results

Possibility to eliminate the influence of the aerosol

Extensive use of different wavelengths for the hardware adaptation of the season

The range weather conditions: summer, spring, autumn.

Advanced application range complex weather conditions and seasons.

Due to the optics you can create a compact and highly directional gauges

Clouds without precipitation can be measured

Possibility of obtaining further information on the lower boundary of clouds and thick clouds using infrared measurements for microwave tomography method

It opens the possibility of estimating the height of cloud and moisture in-cloud layer

Disadvantages

Method are influenced by aerosol, which is difficult to prediction

Method is intended for use in the summer. In winter, its use is extremely limited

Complicated measuring equipment and data processing.

Influenced by cloud cover, which entails limiting the height sensing and difficulties in processing the results of measurements in-cloud layer

Clouds and precipitation require the use of additional wavelengths to account for their influence.

The increase in the price of the complex

The complexity of the calibration at a low level of atmospheric radiation

Highly sensitive

equipment is needed
