ABSTRACT

Ground temperatures in a residential yard used for exercising dogs were measured and evaluated. The study involved four environments (sunny and dry, sunny and watered, shaded and dry, and shaded and watered), each with three measurement spots (green grass, brown grass, and bare ground). Measurements were made at two-hour intervals from 8:00 a.m. to 8:00 p.m. on August 15, 2020. Air temperatures ranged from 82.4 °F at 8:00 a.m. to 100.8 °F at 6:00 p.m. Ground temperatures varied considerably more, from 80.9 °F at bare ground in a shaded and watered spot at 8:00 a.m. to 148.2 °F at brown grass in a sunny and dry spot at 4:00 p.m. Over all times, median temperature ranged from 86.0 °F (range 80.9–87.9 °F) at bare ground in a shaded and watered spot to 125.4 °F (range 86.0–142.8 °F) at bare ground in a sunny and dry spot. For all spots, median ground temperature ranged from 82.6 °F (range 80.9–86.3 °F) at 8:00 a.m. to 128.0 °F (range 87.0–143.7 °F) at 2:00 p.m.

摘要

测量和评估了用于训练狗的住宅庭院的地面温度。该研究涉及四种环境（晴天和干燥、晴天和浇水、阴凉和干燥以及阴凉和浇水），每个环境都有三个测量点（绿草、褐草和裸地）。测量于 2020 年 8 月 15 日上午 8:00 至晚上 8:00 每隔两小时进行一次。气温范围从上午 8:00 的 82.4 °F 到下午 6:00 的 100.8 °F 地面温度变化很大, 从早上 8:00 在阴凉和浇水的裸露地面上的 80.9 °F 到下午 4:00 在阳光充足和干燥的地方棕色草地上的 148.2 °F 80.9–87.9 °F）在阴凉和浇水的裸露地面到 125.4 °F（范围 86.0–142.8 °F）在阳光充足且干燥的裸露地面。对于所有景点，
