Dataset 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.

Dataset 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.

Data Analysis

Climate data can be used as covariates for plot performance.

CSP
name of the CSP in the Nature Reserve. Reasearch plots of the Biodiversity - Ecosystem functioning experiment (BEF-China). There are three main sites for research plots in the BEF Experiment: Comparative Study Plots (CSP) in the Gutianshan Nature Reserve, having a size of 30x30m^2, measured on the ground.

year_isoweek
year of measurement with respect to ISO week, the first week in the year has to include 4 or more days of the new year. Should the first three days of a year happen to be in the last week of the previous year, then year and isoyear are different.

meas_count
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.
