par.to.sw

par.to.sw.base

Returns incoming shortwave radiation by converting PAR measuremt.

methods

math

A collection of tools for the calculation of freewater metabolism
from in situ time series of dissolved oxygen, water temperature, and,
optionally, additional environmental variables. LakeMetabolizer implements
5 different metabolism models with diverse statistical underpinnings:
bookkeeping, ordinary least squares, maximum likelihood, Kalman filter,
and Bayesian. Each of these 5 metabolism models can be combined with
1 of 7 models for computing the coefficient of gas exchange across the
air–water interface (k). LakeMetabolizer also features a variety of
supporting functions that compute conversions and implement calculations
commonly applied to raw data prior to estimating metabolism (e.g., oxygen
saturation and optical conversion models).
