Precipitation measurements from historic and current standard, storage and recording rain gauges at the Andrews Experimental Forest, 1951 to present

Andrews Forest precipitation has been measured continuously using various rain gage types since 1951. Most of these rain gages are standard (non-recording) gages with 7.5 or 8 inch orifices or large capacity storage gages intended for sites with limited access collected irregularly over longer intervals. Recording rain gages have also been established to collect higher temporal resolutions (e.g., 5 minute or 15 minute) and also used as a means of parsing (“prorating”) these periodic interval measurements from these standard and storage gages into daily totals. This data set includes an inventory of all rain gages that have operated within the Andrews as well as one site in the nearby Wildcat RNA and one in the town of Blue River. The inventory includes information regarding the date range of operation, gage location, type of gage, the rain network within which it was established, general availability of data and descriptive notes. A second table includes all of the raw measurement data for these non-recording gages over every interval where data were taken, and additionally includes the corresponding recording gage and its measurement total used to prorate data into a daily record. A third table includes the prorated daily data for all of these standard and storage gages as well as the true daily totals for two recording rain gages. A fourth table includes high temporal resolution for one early recording gage at Forks and the Mack Creek recording gage. Note that while precipitation data associated with the 6 benchmark stations are included in this rain gage inventory (Entity 1), the daily and high temporal resolution data for these sites are available through a separate meteorological data set, database code MS001.

自1951年起，安德鲁斯森林（Andrews Forest）便采用多种雨量计（rain gage）类型持续开展降水观测。其中绝大多数为配备7.5英寸或8英寸口径的标准非自记雨量计，或是专为交通不便站点设计的大容量储水式雨量计，这类设备需间隔较长周期进行不定期数据采集。同时，研究团队还布设了自记雨量计（recording rain gage）以获取更高时间分辨率的观测数据（如5分钟或15分钟分辨率），并将其作为将上述标准及储水式雨量计的周期性时段观测数据按比例折算为日降水总量的辅助手段。本数据集涵盖了安德鲁斯森林范围内所有曾投入运行的雨量计清单，同时包含邻近怀尔德卡特研究自然区（Wildcat RNA）的1个观测站点与蓝河镇的1个观测站点的相关记录。该清单包含如下信息：雨量计的运行日期范围、安装位置、设备类型、所属雨量监测网络、数据整体可用性情况，以及说明性备注。第二张数据表收录了所有非自记雨量计在各观测时段的原始测量数据，同时还附带了用于将这些观测数据折算为日观测记录的对应自记雨量计及其测量总量。第三张数据表包含上述所有标准及储水式雨量计的折算日降水数据，以及两台自记雨量计的真实日降水总量。第四张数据表收录了Forks站点的一台早期自记雨量计与Mack Creek自记雨量计的高时间分辨率观测数据。需注意，尽管6个基准站的降水数据已纳入该雨量计清单（实体1，Entity 1），但这些站点的日数据与高时间分辨率数据需通过独立的气象数据集获取，其数据库代码为MS001。
