A run is when a suite (or system) is executed repeatedly and monitored. Different run types have different permissions, computation priorities, setup instructions, and monitoring conditions according to operational prediction systems tech transfer. Tech transfer describes the processes of moving a run from one type to another type.
An Operational run is continiously monitored and has full operational status.
A pre-operational (or stage) suite is intended to replace the existing parallel suite. . It is first validated against the corresponding parallel one after 24-hour period, and will be archived into the parallel trunk and branches. The soon-to-be-replaced parallel suite will be turned off thereafter.
A parallel run is run alongside (in parallel) to an existing, stable system. The two systems are then compared. Typically, parallel runs do not produce live products delivered to external clients. A parallel suite is setup either wehn there are major improvements, fixes or modifications to an existing operational system, or when there is a new soon-to-be operational system. A parallel run ensures changes and modifications will work and perform as expected withouth impacting the current operational system.
A development run is usally not a monitored system. Development runs are often used to test and evaluate new systems, and monitoring such systems is the responsibility of the developer.
A complete hydro-meteorological prediction system, which aims to provide the best possible representation of the current and future states of the land surface, as well as the movement of water over and through the soil column and through the lake and river networks.
Produces an objective, best estimate of the amount of precipitation that occurred at the surface over recent past periods of 6 or 24 hours. Integrates data from in situ precipitation gauge measurements, weather radar and numerical weather prediction models.
Hourly, ~10-km resolution reanalysis for North America from 1980-2018 of the main meteorological variables that are required for land surface and hydrology applications.
A coordinated database of snow observations, with a primary focus on snow water equivalent data, covering all provinces and territories. Updated annually with a robust, consistent set of quality control measures applied.
