Source-derived summary

The J.S. Marshall Radar Observatory is a McGill University facility in Sainte-Anne-de-Bellevue, Quebec, Canada housing several weather radars and other meteorological sensors, many of them running around the clock. It is one of the components of the McGill Atmospheric and Oceanic Sciences department where students in remote sensing perform their research. The main radar was part of the Canadian weather radar network, on contract with the Meteorological Service of Canada, as well as a research device, up to October 3, 2018.

Editorial summary

This brief starts where responsible research should: with the source description of “J. S. Marshall Radar Observatory” as radar station in Quebec, Canada. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA valuable geographic starting point for tracing changing names, boundaries, uses and administrative responsibility. The current lead gives the account dated anchors—2018—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Marshall, Radar and Observatory can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the places & architecture register because the source frames it as radar station in Quebec, Canada. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Mar 3, 2026. The first chronological checks are 2018.

Critical limits

Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
