Ambient soil temperatures in prescribed burned ponderosa pine forests at Fort Valley Experimental Forest, Arizona

The hourly temperature in the soil at three depths beneath the forest floor of ponderosa pine stands subjected to periodic prescribed burning was measured during one growing season from May until November, 1986 at the Fort Valley Experimental Forest in northern Arizona. Temperatures were measured in 3-day periods at a subset of locations and then the recording devices were moved to a different subset so the measurements at a particular location were separated by about 4 weeks. Additional hourly data from an onsite weather station for air temperature, solar intensity, and precipitation, as well as forest floor depth (6 samples measured above soil temperature site) are included as separate files to assist in site characterization.The objective of this study was to determine the effect of regular prescribed burning on soil temperatures under different overstory classes of ponderosa pine (Pinus ponderosa) located in northern Arizona at the Fort Valley Experimental Forest.Original metadata date was 08/30/2018. On 09/25/2018 we updated the metadata to update the information we were providing regarding the forest floor data file. Additional minor metadata updates made on 05/18/2021.1986年5月至11月的一个生长季内，研究团队于亚利桑那州北部的福特谷实验林（Fort Valley Experimental Forest），对经历定期计划性火烧的北美黄松（Pinus ponderosa）林分的林地下方三个深度的逐时土壤温度开展监测。监测采用分组轮换方式：先在部分测点开展为期3天的温度采集，随后将记录设备转移至另一组测点，因此单个测点的监测间隔约为4周。本数据集还附带现场气象站获取的空气温度、太阳辐射强度、降水量等逐时气象数据，以及林床深度数据（共6个样本，采集于土壤温度监测点上方区域），所有附加数据均以独立文件形式提供，用于辅助站点特征表征。本研究的目标为明确亚利桑那州北部福特谷实验林内，不同冠层等级的北美黄松林地中，定期计划性火烧对土壤温度的影响。本数据集原始元数据日期为2018年8月30日；2018年9月25日，团队针对林床数据文件的相关信息对元数据进行了更新；2021年5月18日，团队又对元数据进行了少量额外修订。
