Executive Findings
- The public-source Nordic fixed weather-radar estate totals at least 42 active sites: Norway 11, Sweden 12, Finland 12, Denmark 5, and Iceland 2.
- Every fixed Nordic weather radar validated in the research pass is a C-band system; no verified Nordic public S-band weather-radar asset was found in the accessed sources.
- Finland, Sweden, and Denmark have the clearest modernization story: all three public records point to dual-polarization C-band Doppler networks.
- Norway's reopened WMO Weather Radar Database entries point to a mostly Selex C-band magnetron estate operated by MET Norway, with coastal and Arctic sites central to the public metadata trail.
- Iceland's public radar story is tightly coupled to aviation and volcanic-ash monitoring, especially Keflavik/Midnesheidi and the 2011 mobile ash-radar deployment near Grimsvotn.
Modernization Notes
Reopened WRD entries show magnetron transmitters, roughly 5.62-5.64 GHz operation, 1.0 degree beamwidth, and scan strategies from 0.5 to 35 degrees.
Full WRD detail was reopened for Andoya, Hasvik, Berlevag, and Stad. The remaining Norwegian sites are represented as operational-indexed until their detail pages are transcribed.
The 2023 anomalous-propagation study documents recent single-pol to dual-pol modernization and gives dated refits for five coastal nodes.
The research pass recovered coordinates for 11 named rows and confirmed a 12-radar active total; one active SMHI site remains unnamed in the accessible extract.
FMI states 5600-5650 MHz magnetron operation, 4.5 m antennas, 6.7 m radomes, and annual data availability above 98 percent.
The current FMI list differs from older online examples. Uto is treated as historical context, not a current official FMI radar node.
DMI's 2024 Samso note states that all five current radars are Vaisala dual-polarization Doppler C-band systems.
Samso is current but exact decimal coordinates were not exposed in the accessed public sources. Virring is retained as a superseded historical node.
The eastern radar was publicly described as added in 2012; Keflavik remains the central precipitation, aviation, and ash-cloud monitoring reference.
The accessed official pages did not expose exact public decimal coordinates for the fixed Icelandic radars.
