monica-adapter v1.0.0

nodejs-monica-adapter

Node.js adapter to use the "model for Nitrogen and Carbon in agricultural systems" from ZALF Muencheberg, Germany

Requirements

You need to install monica and two by monica required packages: https://github.com/zalf-lsa/monica https://github.com/zalf-lsa/util https://github.com/zalf-lsa/sys-libs

Additionally install monica-parameters to use predefined crop, cultivar, residue etc. parameters. https://github.com/zalf-lsa/monica-parameters

Installation

Simply install this module with npm

npm install nodejs-monica-adapter

To install it globally run

npm install -g nodejs-monica-adapter

Usage

You have to compose your own "env" json object with all the information needed for a monica calculation. The Node.js adapter uses monica-zmq-server. Monica server processes are forked in the background and calculation data is sent to these processes. Communication is handled by "zero message queue".
