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) ....

data(amd)

A data frame with 559 observations on the following 14 variables.

`timestamp`

POSIXlt representing the date and time for the measurements

`campaign`

Numeric. 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)

`plot`

Numeric. Representing the field plot numbers

`kind`

Character 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)`flux`

Numeric. The estimated flux rate. CO2 exchange in micromole per sqm and second

`PAR`

Numeric. Average photosynthetically active radiation during the flux measurement. Actually represents PPFD (photon flux density) in micromole per sqm and second

`t.air`

Numeric. Average air temperature during chamber measurement in °C

`t.soil2`

Numeric. Average soil temperature in 2cm depth during chamber measurement in °C

`t.soil5`

Numeric. Average soil temperature in 5cm depth during chamber measurement in °C

`t.soil10`

Numeric. Average soil temperature in 10cm depth during chamber measurement in °C

`n.meas`

Numeric giving the number of concentration measurements that were available to estimate the flux

`duration`

Factor with 282 levels giving the duration of measurement in the field, format is "%H:%M"

`r.squared`

Numeric. The R2s of the linear regression models that were fit to the concentration data to estimate the fluxes (with

`fluxx`

)`sigmif`

Numeric. The significance of the linear regression models
