资源简介:
Complete database of high-frequency sampling of rainfall events in the Rio Claro, São Paulo State, Brazil, between 2019 and 2021. Local: Rio Claro, state of São Paulo, Brazil (-22.39°S, -47.54°W, 670 m a.s.l.). File contents: 32 columns and 202 rows Units of measurement given in the table for each parameter. Isotopic data: oxygen-18, deuterium and excess deuterium (permil unit); Collected every 5-10-30 minutes depending on rainfall intensity. Meteorological data: Decagon Automatic Weather Station (AWS) Em50 including rain rate (ARR, mm), temperature (T, °C), relative humidity (RH, %), dew point (Tdew), lifting condensation level (LCL, m) was calculated using AWS RH and T data following Soderberg et al. (2013). - Micro Rain Radar (MRR-2, METEK): Reflectivity (Z, dBZ), fall velocity (w, m s-1), liquid water content (LWC, g m-3), and radar rain rate (Rrr, mm). Measurements closer to the surface, between 150 and 350 meters. - GOES-16 band 13 satellite: brightness temperature, taken every 10 minutes.

巴西圣保罗州里奥克拉鲁(Rio Claro)地区2019至2021年降雨事件高频采样完整数据库。
数据集采集地点:巴西圣保罗州里奥克拉鲁,坐标为-22.39°S、-47.54°W,海拔670米。
数据集文件结构:共包含32列、202行,各参数的测量单位详见数据表格。
同位素数据:涵盖氧-18、氘以及氘过量参数,单位为千分比(permil);采样间隔依据降雨强度设置为5分钟、10分钟或30分钟。
气象数据包含三类观测结果:
1. Decagon自动气象站(Automatic Weather Station, AWS)Em50采集数据:包含降雨率(ARR,单位:mm)、气温(T,单位:℃)、相对湿度(RH,单位:%)、露点温度(Tdew);抬升凝结高度(Lifting Condensation Level, LCL,单位:m)依据Soderberg等人(2013)提出的方法,利用该自动气象站采集的相对湿度与气温数据计算得到。
2. 微雨雷达(Micro Rain Radar, MRR-2,METEK公司)观测数据:包含反射率(Z,单位:dBZ)、粒子下落速度(w,单位:m·s⁻¹)、液态水含量(LWC,单位:g·m⁻³)以及雷达降雨率(Rrr,单位:mm),观测高度贴近地表,范围为150米至350米。
3. GOES-16卫星第13波段数据:亮温,采集间隔为10分钟。
