Closed chamber fluxes from 2009 to 2011 in the Ahlenmoor peat bog, Northeast Germany
Description
CO2 exchange rates determined with closed chamber measurements and cooresponding measurements of temperatures, photosynthetically actiove radiation, and other variables in the Ahlen-Falkenberger Moor peat bog complex from 2009 to 2011 on one specific plot (3 replicates) ....
Usage
data(amd)
Format
A data frame with 559 observations on the following 14 variables.
timestampPOSIXlt representing the date and time for the measurements
campaignNumeric. Representing IDs of the measurement campaigns, i.e. data sharing on campaign were acquired within short time period (typically one day but sometimes also two consecutive days)
plotNumeric. Representing the field plot numbers
kindCharacter vector giving the kind of chamber measurements. Either "D" for dark (opaque) chamber measurements (i.e., R_eco measurements) or "T" for transparent chamber measurements (i.e., NEE measurements)
fluxNumeric. The estimated flux rate. CO2 exchange in micromole per sqm and second
PARNumeric. Average photosynthetically active radiation during the flux measurement. Actually represents PPFD (photon flux density) in micromole per sqm and second
t.airNumeric. Average air temperature during chamber measurement in °C
t.soil2Numeric. Average soil temperature in 2cm depth during chamber measurement in °C
t.soil5Numeric. Average soil temperature in 5cm depth during chamber measurement in °C
t.soil10Numeric. Average soil temperature in 10cm depth during chamber measurement in °C
n.measNumeric giving the number of concentration measurements that were available to estimate the flux
durationFactor with 282 levels giving the duration of measurement in the field, format is "%H:%M"
r.squaredNumeric. The R2s of the linear regression models that were fit to the concentration data to estimate the fluxes (with fluxx)
sigmifNumeric. The significance of the linear regression models
