New section 4 templates to extend the base chemical constituents and aerosol templates to encode derived products, probabilities and quantiles #345
Description
Introduction
For chemical and aerosol parameters, only few templates for base products are defined as product definition templates. It is not possible to encode derived forecasts (e.g., for ensemble mean / spread), probability (e.g., exceedance of a certain concentration of substance xy) and quantiles (e.g., 90th percentile of forecast PDF of the concentration of substance xy). The existing templates for which no derived forecast, probability and quantile versions exist are listed in the following table:
| Code | Description |
|---|---|
| 4.41 | Individual ensemble forecast, control and perturbed at a horizontal level or in a horizontal layer at a point in time for atmospheric chemical constituents |
| 4.43 | Individual ensemble forecast, control and perturbed at a horizontal level or in a horizontal layer in a continuous or non-continuous time interval for atmospheric chemical constituents |
| 4.45 | Individual ensemble forecast, control and perturbed at a horizontal level or in a horizontal layer at a point in time for aerosol |
| 4.49 | Individual ensemble forecast, control and perturbed at a horizontal level or in a horizontal layer at a point in time for optical properties of aerosol |
| 4.77 | Individual ensemble forecast, control and perturbed at a horizontal level or in a horizontal layer at a point in time for atmospheric chemical constituents with source or sink |
| 4.79 | Individual ensemble forecast, control and perturbed at a horizontal level or in a horizontal layer in a continuous or non-continuous time interval for atmospheric chemical constituents with source or sink |
| 4.81 | Individual ensemble forecast, control and perturbed at a horizontal level or in a horizontal layer at a point in time for optical properties of aerosol with source or sink |
| 4.84 | Individual ensemble forecast, control and perturbed at a horizontal level or in a horizontal layer in a continuous or non-continuous time interval for aerosol with source or sink |
| 4.85 | Individual ensemble forecast, control and perturbed at a horizontal level or in a horizontal layer in a continuous or non-continuous time interval for aerosol |
We propose to extend these templates by adding the relevant extra keys to encode derived products, probabilities and quantiles.
