该数据集记录了阿里荒漠环境综合观测研究站，2009-2017年气象数据集，数据时间分辨率为天。包含如下基本气象参数：气温（距地面1.5米，半小时观测一次，单位：摄氏度）、相对湿度（距地面1.5米，半小时一次，单位：%）、风速（距地面1.5米，半小时一次，单位：米/秒）、风向（距地面1.5米，半小时一次，单位：度）、气压（距地面1.5米，半小时一次，单位：hPa）、降水量（24时一次，单位：毫米）、水汽压（单位：Kpa）、蒸发（单位：毫米）、向下短波辐射（单位：W/m²）、向上短波辐射（单位：W/m²） 、向下长波辐射（单位：W/m²） 、向上长波辐射（单位：W/m²） 、净辐射（单位：W/m²）、地表反照率（单位：%）。
数据采集地点：中国科学院青藏高原研究所阿里荒漠环境综合观测研究站观测场，经度：79°42'5"；纬度：33°23'30"；海拔：4264米。
数据从阿里站自动气象站直接下载，其中降水数据是自动雨雪量计和人工观测校正得到每天的降水量，其它均为半小时的观测值经平均得到逐日均值。
观测仪器型号：温度和湿度：HMP45C空气温湿度探头；降水：T200-B雨雪量仪传感器；风速和风向： Vaisala 05013风速风向传感器；净辐射：Kipp Zonen NR01净辐射传感器；气压：Vaisala PTB210大气压传感器。采集器型号：CR 1000，采集时间：30分钟。
本数据表是由专人根据观测记录进行加工和质量控制。严格按照仪器操作规范进行观测和数据采集，在加工生成数据表时，剔除了一些明显误差数据。

This dataset is a daily meteorological dataset collected at the Ali Desert Environment Comprehensive Observation and Research Station from 2009 to 2017, with a daily temporal resolution. It includes the following basic meteorological parameters:
1. Air temperature: measured at 1.5 meters above the ground, observed every 30 minutes, unit: degrees Celsius
2. Relative humidity: measured at 1.5 meters above the ground, observed every 30 minutes, unit: %
3. Wind speed: measured at 1.5 meters above the ground, observed every 30 minutes, unit: m/s
4. Wind direction: measured at 1.5 meters above the ground, observed every 30 minutes, unit: degrees
5. Atmospheric pressure: measured at 1.5 meters above the ground, observed every 30 minutes, unit: hPa
6. Precipitation: measured once daily at 24:00, unit: millimeters
7. Vapor pressure: unit: kPa
8. Evaporation: unit: millimeters
9. Downward shortwave radiation: unit: W/m²
10. Upward shortwave radiation: unit: W/m²
11. Downward longwave radiation: unit: W/m²
12. Upward longwave radiation: unit: W/m²
13. Net radiation: unit: W/m²
14. Surface albedo: unit: %

Data collection site: Observation field of the Ali Desert Environment Comprehensive Observation and Research Station, Institute of Tibetan Plateau Research, Chinese Academy of Sciences, with coordinates of 79°42'5" E, 33°23'30" N, and an altitude of 4264 meters.

The data was directly downloaded from the automatic weather station at the Ali Station. Precipitation data was corrected using automatic rain/snow gauge and manual observations to derive daily precipitation values, while other parameters were calculated as daily averages from 30-minute interval observations.

Observation instrument models:
- Temperature and humidity: HMP45C air temperature and humidity probe
- Precipitation: T200-B rain/snow gauge sensor
- Wind speed and direction: Vaisala 05013 wind speed and direction sensor
- Net radiation: Kipp & Zonen NR01 net radiation sensor
- Atmospheric pressure: Vaisala PTB210 atmospheric pressure sensor
Data logger model: CR1000, with a sampling interval of 30 minutes.

This dataset was processed and quality-controlled by dedicated personnel based on the original observation records. Observations and data collection were conducted strictly in accordance with the instrument operation specifications, and any obvious erroneous data was removed during the dataset generation process.
