Given zOffsets, diffusivity, and co2 (umol mol-1) and their associated errors, compute the surface flux. This is done by linear extrapolation of surface fluxes. Modified from Tang et al (2005).
tang_2005_flux(zOffset, co2, co2_err, diffusive, diffusive_err)
zOffset |
Required. depths below surface - assumed to be positive in value. Important for directionality! |
co2 |
Required. co2 at depth (umol m–1) |
co2_err |
Required. Associated errors with that value of co2 |
diffusive |
Required. diffusivity at each depth |
diffusive_err |
Required Associated errors with diffusivity |
Data frame of fluxes associated error
