This data set is the daily scale artificial evaporating dish and precipitation data of Qilian station from January 1, 2012 to December 31, 2012. It contains an excel file hulugou basin 2012 artificial evaporating dish and precipitation data set. There are data and instructions in xlsx. Precipitation is generally observed in two-stage system, that is, at 8:00 and 20:00 every day. Observation sections are added in rainy season, and additional observation is needed when the rainfall is heavy. The daily rainfall is divided by 8:00 a.m. every day, and the precipitation from 8:00 a.m. today to 8:00 a.m. the main collection indexes are < p > this data set is the daily scale artificial evaporating dish and precipitation data of Qilian station from January 1, 2012 to December 31, 2012.

The daily rainfall is divided by 8:00 a.m. every day, and the precipitation from 8:00 a.m. today to 8:00 a.m. the next day is taken as the daily precipitation. The main collection indexes are date, precipitation (20cm) and evaporation (20cm) mm.

(1) The evaporation capacity is measured by 20 special measuring cup at 20:00 every day; generally, the special measuring cup is used to measure the fresh water 20 mm (the original volume) and poured into the device at 20:00 the previous day, and the water volume (the margin) in the re measuring device 24 hours later, that is, at 20:00 the same day, the reduced volume is the evaporation capacity. That is: evaporation = original amount - allowance. If there is precipitation between 20:00 of the previous day and 20:00 of the current day, the calculation formula is: evaporation = original amount + precipitation - allowance.
