日常气候数据的 csv2bufr 模板（DAYCLI）
DAYCLI 模板提供了一个标准化的 CSV 格式，用于将日常气候数据转换为 BUFR 序列 307075。
该格式旨在与气候数据管理系统一起使用，以支持在 WIS2 上发布数据，以满足日常气候观测的报告要求。
此模板映射了每日观测数据：
- 24小时内的最低、最高和平均温度
- 24小时内的总降水量
- 观测时的总积雪深度
- 24小时内的新雪深度
此模板需要额外的元数据，相对于简化的 AWS-模板：计算平均温度的方法；传感器和站点高度；暴露和测量质量分类。
关于 DAYCLI 模板
请注意，DAYCLI BUFR 序列将在 2025 年更新，以包括额外信息和修订的质量控制标志。包含在 wis2box 中的 DAYCLI 模板将更新以反映这些变化。WMO 将通知何时更新 wis2box-软件以包含新的 DAYCLI 模板，以便用户相应更新其系统。
