What products are available in the Arctic in between SAR observations? Consider the composite image above, showing RADARSAT-2 SAR ice concentration at 0453 UTC on 22 February 2023 over/around Saint Matthew Island (direct link to footprint here at the STAR SAR Wind site*) and an RADARSAT Constellation Mission-3 (RCM3) image at at 0546 UTC on 22...

GOES-16 (GOES-East) Air Mass RGB images (above) included contours of RAP40 model PV 1.5 Pressure — and showed a Hurricane Force low pressure that had rapidly intensified as it moved northeastward off the US East Coast (surface analyses) on 06 February 2023. The PV 1.5 surface (which represents the dynamic tropopause) descended to the 500 hPa pressure level at... Read More
GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) include plots of GOES-16 Derived Motion Winds (DMW) within the 775-900 hPa and the 900 hPa-Surface layers — which displayed a rapidly-intensifying area of low pressure (surface analyses) over the West Atlantic Ocean (south of Nova Scotia, Canada) on 12 December 2022. Note the area of haziness just... Read More
