Hydrometric, tracer, and modeled discharge data from headwater catchments in central Costa Rica

This dataset integrates long-term (2013-2026) hydrometric, tracer, and modeled discharge data across eleven headwater catchments and spring systems spanning the Caribbean and Pacific domains of north-central Costa Rica (from 1,471 to 2,430 m asl). The data files include water level and temperature measurements, water isotopes compositions, physical-chemical parameters, and observed and modeled discharge.本数据集整合了哥斯达黎加中北部加勒比与太平洋片区内11处源头集水区及泉系的长期（2013—2026年）水文测量、示踪剂与模拟径流数据，研究区域海拔跨度为1471至2430 m asl。数据集文件涵盖水位与温度监测数据、水体同位素组成、理化参数，以及实测与模拟径流数据。
