Cerrado Tree Physiology and Microclimate Data from Passive Heating Chambers 2020

June to September 2020 data from a Cerrado study in Brazil includes minute-level temperature and relative humidity readings inside and outside passive heating chambers. Respiration and photosynthesis rates were measured on Erythroxylum suberosum leaves at controlled temperatures, alongside 15-minute weather station data for solar irradiance.

Use Cases

• Compare minute-level temperature and relative humidity readings inside versus outside open top chambers to validate passive heating methodology.
• Analyze the relationship between controlled leaf temperature measurements and recorded respiration and photosynthesis rates.
• Correlate 15-minute solar irradiance data from the local weather station with chamber microclimate conditions.
• Model whole-tree physiological responses to daytime warming using combined chamber and weather station time series data.

Strengths

• High temporal resolution with minute-level recordings for chamber temperature and relative humidity.
• Multi-source data integration combining chamber microclimate, leaf physiology, and local weather station measurements.
• Data collected over a defined four-month period from June to September 2020 in a specific Cerrado study area.

Limitations

• Unknown sample size for study individuals and total number of recorded observations.
• Geographic scope is limited to a single study site in Bacaba Park, Nova Xavantina, Brazil.
• Data is temporally static, covering only one season in 2020 without ongoing updates.
