Microclimate data associated with green infrastructure in Lancaster Pennsylvania, 2022

Green stormwater infrastructure (GSI) is being increasingly implemented as a stormwater management practice. A key reason for its popularity is the potential for co-benefits, such as heat mitigation, in addition to stormwater management functions. This data is the result of field investigation of heat patterns around GSI in Lancaster, Pennsylvania, providing some of the first ever direct measurements of microclimate and thermal comfort near GSI. During summer 2022, we collected data along transects at 10 rain gardens. Microclimate variables were quantified using a Kestrel 5400 Heat Stress Tracker and were used to calculate metrics that represent heat stress experienced by a human such as wet bulb globe temperature (WBGT) and mean radiant temperature (MRT). Measurements were also made at nearby impervious surface and lawn reference sites.
