Comparison of manual and automatic measurements leof air and soil temperature in the Czech Republic

Differences between manual and automatic measurements of air temperature and soil temperature should not be neglected. The average difference between the manual and the automatic measurements of air temperature varied between 0.3 and 2.8 degrees C during suitable weather conditions (wind speed less than 3 m/s, bright and sunny day) throughout the year, during both daytime and nighttime hours. Comparative measurements showed that average monthly differences of air temperature between manual and automatic measurements varied between -0.5 and 0.29 degrees C; differences of soil temperatures at a depth of 5, 10 and 20 cm between 0.3 and 0.83 degrees C, respectively at a depth 50 and 100 cm between -0.13 and 0.28 degrees C.
