Abstract
With maximum temperature and maximum temperature of the ground observation method comparison and analysis of observational da-ta, and using the knowledge of electromagnetism to explain cause auto-contrast observation ground station and manual maximum temperature error is often the root cause of a larger, draw reasonable conclusions, and study new methods of observation. The results indicated that; the most im-portant factors causing large errors are automatically stops platinum resistance thermometer and the mercury thermometer and a smooth surface material led to the different levels of sunlight in different albedo and absorption, causing large automatic stations and manual observation error. Platinum resistance thermometer seriously affected by solar radiation. Several solutions were put forward: a. The maximum temperature observed simulation method, by simulating the effect of thermometer screen, shielding solar radiation, without affecting the platinum resistance thermome-ter and mercury thermometer sensor part of the normal absorption of solar radiation in the soil around the case, making the two collection devices, to avoid solar radiation, the normal surface temperature sensor; b. Thermometer in the acquisition and covered with a thin layer of thermal part of the observation field can make the collection of soil and surface albedo for more similar and closer to the surface of the beat-absorbing proper-ties , to obtain more accurate observations.关键词
