Description Usage Arguments Value
Downward Longwave Radiation from a emissivity and a cloud cover schemes
1 2 3 |
data_ |
Data frame with column of date (date), temperature (Ta), partial vapor pressure (es), potencial radiation (Rpot), relative humidity (rh), atennuation index (K) |
E_fun |
Emissivity scheme |
C_fun |
Cloud cover scheme |
adjust |
FALSE, TRUE if nonlinear least square adjusting wanted |
method |
"non-linear" (default) for Non linear Least Square adjust, "montecarlo" for MonteCarlo optimization. Later be usseful when a NLS can't adjust observed data allowing optimization. |
nsample |
population number evaluated in each iteration (only when method = "montecarlo"). |
max_iter |
maximun number of iterations (only when method = "montecarlo"). |
stats |
statistical function to be minimized (only when method = "montecarlo"), NOTE: the best result should be 0.0 (ex., if stats = r (correlation), then transform to rMod = 1.0 - r, so the best result is when r== 1.0, so rMod == 0.0) |
log_file |
path to a log file |
ret_coefs |
Return coeficients from adjusting, in this case a list contein both information: estimated Li and coeficients used or determined. |
forced |
Forced adjust, default TRUE |
Vector with Downward Longwave Radiation time series
