Abstract

We installed a meteorological recording system at Badwater (elev. −75 m), the lowest point in Death Valley, California and recorded data over the period 1998–2019. A second station (the Outhouse Station) was established nearby from 2014 to 2019. Here, we report on and publicly archive the data from these two stations. Of interest was the comparison between two air temperature measurements at the Badwater Station, the first with an aspirated platinum resistance temperature device and the second with a thermistor probe in a passive sun shield. During the hottest periods of the summer when temperatures were typically between 30°C at night and 50°C daily peak, the passively shielded sensor indicated up to 0.5°C warmer than the aspirated temperature sensor due to radiative effects. The data suggest a correction for radiative heating of (T–35)/30, for T > 35°C, where, T, is the uncorrected temperature reading of a passively shielded sensor subtracted after any calibration at lower temperatures. Our station was the first precision temperature measurements at Badwater. A longer record exists for the reporting station near the visitor's centre at the Furnace Creek. The summer temperature maxima at the Badwater site correlate well with the values the same day from the Furnace Creek site. The daily maximum temperatures in winter at the Badwater site appear to be about 1°C lower than at the Furnace Creek site. The largest differences are in the minimum temperatures for which the Badwater site averages about 2–3°C warmer than the Furnace Creek site.

死亡谷国家公园巴德沃特 1998 年至 2019 年的气象数据
我们在加利福尼亚州死亡谷的最低点 Badwater(海拔-75 米)安装了气象记录系统,并记录了 1998-2019 年期间的数据。从 2014 年到 2019 年,我们在附近建立了第二个站点(厕所站点)。在此,我们对这两个站点的数据进行了报告和公开存档。值得关注的是对巴德沃特站两次气温测量结果的比较,第一次是使用吸气式铂电阻温度测量仪,第二次是使用被动遮阳板中的热敏电阻探头。在夏季最热的时期,夜间温度通常在 30°C 和日最高温度 50°C 之间,由于辐射效应,被动式遮阳板传感器显示的温度比吸气式温度传感器高出 0.5°C。数据表明,在 T > 35°C 时,辐射加热的校正值为 (T-35)/30,其中,T 是被动屏蔽传感器在较低温度下校正后减去的未校正温度读数。我们的站点是巴德沃特的第一个精确温度测量点。古炉溪游客中心附近的报告站有更长的记录。巴德沃特站点的夏季最高气温与古炉溪站点的同日最高气温有很好的相关性。巴德沃特观测点冬季的日最高气温似乎比古炉溪观测点低约 1°C。差异最大的是最低气温,巴德沃特站点的最低气温比古炉溪站点平均高出 2-3°C 左右。

期刊介绍: Geoscience Data Journal provides an Open Access platform where scientific data can be formally published, in a way that includes scientific peer-review. Thus the dataset creator attains full credit for their efforts, while also improving the scientific record, providing version control for the community and allowing major datasets to be fully described, cited and discovered. An online-only journal, GDJ publishes short data papers cross-linked to – and citing – datasets that have been deposited in approved data centres and awarded DOIs. The journal will also accept articles on data services, and articles which support and inform data publishing best practices. Data is at the heart of science and scientific endeavour. The curation of data and the science associated with it is as important as ever in our understanding of the changing earth system and thereby enabling us to make future predictions. Geoscience Data Journal is working with recognised Data Centres across the globe to develop the future strategy for data publication, the recognition of the value of data and the communication and exploitation of data to the wider science and stakeholder communities.
