Penman-Monteith-Leuning Evapotranspiration (ET) Version2 in R

Dongdong Kong, CUG

R-CMD-check codecov

TODO

  • 以NorthChina为输入,测试PMLV2的核心代码;

  • 植被驱动数据,等待GEE跑完Albedo,然后进行线性插值、历史平均插值处理;

  • 气象驱动数据,从GEE截取,tiff转nc;

  • 模型参数率定,截取通量站驱动数据,重新率定模型参数(ERA5L, GLDASv2.1, GLDASv2.2, CFSV2, MERRA2);

Installation

You can install the development version of PMLV2 like so:

remotes::install_github("gee-hydro/PMLV2")

pak::pkg_install(c("phenofit"))
pak::pkg_install(c("rpkgs/rfluxnet", "rpkgs/nctools"))

Example

See the following instruction:

https://gee-hydro.github.io/PML.R/articles/model_forcing.html

https://gee-hydro.github.io/PML.R/articles/run_model.html
