In the test base, Carry out comparative tests on data acquisition rate, accuracy and cloud base height recognition ability of cloud radar, lidar-MPL, laser ceilometer, radio sonde, so as to improve the cloud base height recognition ability. under different cloud types and different weather conditions. Preliminary conclusion: The cloud base of the cloud radar is lower by -0.5%, and the laser ceilometer is higher by 5%，compared with cloud base height of the sounding.

Carry out ground test satellite cloud top height

Comparative observations of cloud radar and satellite cloud heights were carried out at seven integrated stations in Beijing to verify the accuracy of satellite cloud inversion from different cloud heights, cloud thickness and precipitation. Preliminary conclusion: High cloud is lower than 2km, medium cloud is lower than 0.79km and High cloud on the high side 0.67km , Satellite compared to cloud radar.

 Evaluation method of temperature and humidity profile

  • 1. Comparison of brightness temperature(Observation simulation)

Comparison of Different Type of Microwave Radiometers

Deviation of O-B brightness temperature in clear sky sample

  • Under clear sky conditions, the average of mean

square root between the observational and simulated brightness temperature of the four type radiometers is 3.02K.

  • The RPG radiometer shows the smallest error of

brightness temperature.

  • Average error between temperature and L-band

sounding is about 2K.

  • average error of humidity and sounding is about 20%.
  • Cloudy conditions error is greater than clear-sky
