Returns the gas exchange velocity for gas of interest w/ no unit conversions
1 2 3 | k600.2.kGAS.base(k600,temperature,gas="O2")
k600.2.kGAS(ts.data, gas="O2")
|
k600 |
k600 as vector array of numbers or single number |
temperature |
Water temperature (deg C) as vector array of numbers or single number |
gas |
gas for conversion, as string (e.g., 'CO2' or 'O2') |
ts.data |
Object of class data.frame with named columns datetime and k600 and wtr (water temp in deg C). Other columns are ignored |
Numeric value of gas exchange velocity for gas
Jordan S. Read
k.read and k.read.base for functions that calculate k600 estimates

kO2 <- k600.2.kGAS.base(k600=2.4,temperature=20.4,gas='O2')
## Timeseries example
#load data
data.path = system.file('extdata', package="LakeMetabolizer")
sp.data = load.all.data('sparkling', data.path)
ts.data = sp.data$data #pull out just the timeseries data
#calculate U10 and add it back onto the original
u10 = wind.scale(ts.data)
ts.data = rmv.vars(ts.data, 'wnd', ignore.offset=TRUE) #drop old wind speed column
ts.data = merge(ts.data, u10) #merge new u10 into big dataset
k600 = k.cole(ts.data)
ts.data = merge(k600, ts.data)
k.gas = k600.2.kGAS(ts.data, 'O2')
