Abstract:
The accompanying file is an aggregate of the data from June 2011 to September/October 2011. Microclimate data from all 27 CSPs. Climate data consists of relative air humidity and air tempreature. Weekly means are given and were calulated from 15 min interval measurements.
Design:
Climate data was automatically measured and recorded within the timrange every 15 minutes from June 2011 until September/October 2011 and every 30 minutes thereafter. One logger was placed in each CSP in one of the corners. Corners were selected randomly. Logger specification: HOBO U23 Pro v2 Temperature/Relative Humidity Data Logger - U23-001, Chanel 1: internal temperature sensor: -40...+70 °C, Accuracy ±0,2 °C at 21 °C, Chanel 2: internal humidity sensor: 0...100 %rF, Accuracy ±2,5 %rF
Spatial extent:
CSPs, Gutianshan National Nature reserve
Temporal extent:
Data was measured and recorded with data loggers during the timespan June to October 2011 in 15 min intervals and between October 2011 and October 2012 in 30 min intervals
Taxonomic extent:
No species information, this is the plot related data.
Measurement cirumstances:
No information available
Data analysis:
Climate data can be used as covariates for plot performance.

Dataset column

Name:
meas_count
Definition:
number of measurements aggregated to the ISO week 8601, maximum count of quarter hour intervals in one week is 672, thus, weeks with less measurements give a biased mean, maximum, or minimum value. This therefore can be considered to be some kind of quality indicator to the respective aggregated values.
