New Design of Simulations

Calibration with many sites to obtain best performance using a common set of parameters values for all sites

  • by pej
  • Posted on July 5, 2020
  • Bug Fixed

This procedure is based on using more than 2 dimension of a Multirun where the first dimension is used to specify the site specific parameters and the second is used to specify those parameters that […]

  • Posted on December 20, 2019
  • New Design of Simulations

The new version 6.1.0 of the model includes a new option that allows simple extrapolation into the future based on the previous year. To perform such a simulation we need climate data from a complete […]

Deleted bug for solar angle and new error test

  • by pej
  • Posted on March 5, 2019
  • Bug Fixed

Simulations have not been perfectly stable and to some extent this is because of many new implementations of functions objects. To identify numerical problems with may be partly random a new error test have been […]

New options for Sensitivity Analysis – constrain by parameters

  • by pej
  • Posted on January 19, 2019
  • New Design of Simulations

MultiRuns with the CoupModel are mostly linked with some type of uncertainty based method to constrain the model outputs based on the agreement between one or more model outputs with corresponding measurements. This is done […]

New aggregation control to design calibration

  • by pej
  • Posted on October 18, 2018October 18, 2018
  • New Design of Simulations

Normally a calibration using Multirun options are made using New candidates  of parameter values for each run. However, in case of trying to find common parameter values for various runs as represented by a deterministic […]

New version with features for Multi Calibration of time series origination from various sites

  • by pej
  • Posted on June 7, 2017June 7, 2017
  • New Design of Simulations

The new version is making use of PG-files with repetitions to make a simple running of many sites. A preliminary example prepared by help from Mousung Wu is using 10-flux-sites to calibrate the model for […]
