snow pit data in Altay (2015/2016)-National Tibetan Plateau Data Center

Snow pits were observed daily at Altay base station（lon：88.07、lat: 44.73） from November 27, 2015 to March 26, 2016. Parameters include: snow stratification, stratification thickness, density, particle size, temperature. The frequency of observation was daily. The particle size was observed by a microscope with camera, the density was observed by snowfork, snow shovel and Snow Cone, and the temperature was automatically observed by temperature sensor. The observation time was 8:00-10:100 am local time. The snow particle size is observed according to the natural stratification of snow. The snow particles of each layer are collected, and at least 2 photos are taken. The long axis and short axis of at least 10 groups of particles are measured by corresponding software. Unit: mm. The density was observed at equal intervals, snowfork every 5 cm, snow shovel every 10 cm, snow cone to observe the density of the whole snow layer, and the density of each layer was observed three times. The unit is g / cm3. The height of temperature observation is 0cm, 5cm, 10cm, 15cm, 25cm, 35cm, 45cm, 55cm. The recording frequency was once every 1 minute. The unit is OC.

Data file naming and use method

File name: the data has been stored in Excel. It is divided into three files, named layering, snow density and snow temperature, which respectively store the data of stratification thickness and particle size, snow density and snow temperature.
The layering table contains the daily snow layer thickness and the particle size of each layer.
The snow density table contains three kinds of daily density: the density per 5cm observed by snow fork, the density per 10cm observed by snow shovel, and the density of the whole snow layer observed by snow cone.
The snow temperature table contains the temperature at different altitudes observed by the temperature sensor every 1 minute. 0cm is the temperature of snow / soil interface, 5cm is the temperature of snow at 5cm height, 10cm is snow temperature at 10cm height, 20cm is snow temperature at 20cm height, 30cm is snow temperature at 30cm height, 40cm is snow temperature at 40cm height and 50cm is snow temperature at 50cm height
Data reading method: open directly with Excel
