Regional Ensemble Storm Surge Prediction System (RESPS) data in NetCDF format

This page describes the Regional Ensemble Storm Surge Prediction System data available in NetCDF format.

Data location

MSC Datamart data can be automatically retrieved with the Advanced Message Queuing Protocol (AMQP) as soon as they become available. An overview and examples to access and use the Meteorological Service of Canada's open data is also available.

The data is available via the HTTPS protocol. It is possible to access it with a standard browser. In this case, we obtain a list of links giving access to a NetCDF file.

The data can be accessed at the following address :

where :

  • HH : Model run start, in UTC [00 or 12]

A history of 24 hours is maintained in this directory.

Grid technical specification

This table lists the values of different parameters of the RESPS grid:

Parameter Value
ni 333
nj 217
resolution 0.083° x 0.083°

Nomenclature of file directories


File names have the form:



  • YYYYMMDD: Year, month and day of the beginning of the forecast
  • T : Time delimiter according to ISO8601 norms
  • HH: UTC run time [00, 12]
  • Z : Time zone (UTC hour)
  • MSC : Constant string indicating the Meteorological Service of Canada, source of data
  • RESPS-Atlantic-North-West : Constant string indicating that data is from the Regional Ensemble Storm Surge Prediction System over the North-West domain
  • VAR : Variables included in the file [ETAS, SSH]
  • LVL : Vertical level [Sfc for the surface]
  • Grille : Horizontal grid lat-lon [LatLon]
  • Resolution : Indicating resolution in degreee in latitude and longitude directions [0.083]
  • PT{hhh}H: Forecast hours based on ISO8601 norms. P, T and H are constant character designating Period, Time and Hour. "hhh" is the forecast hour [000, 001, 002, ..., 240]
  • nc: constant string indicating the NetCDF format is used
