GOES-16 (GOES-East) “Clean” Infrared Window (10.3 µm) images with plots of SPC storm reports are shown above; a Mesoscale Sector was positioned over the region, providing images... Read More
An organized area of low pressure (Invest 90E) developed in the East Pacific Ocean on 08 May 2018 — the NHC gave it a 50% chance of becoming a tropical depression within 48 hours. GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) showed the formation of a large convective burst in the... Read More
Sea Surface Temperatures (SSTs) produced from the Advanced Clear-Sky Processor for Oceans (ACSPO) are now being created in real time at the National Weather Service Forecast Office on Guam (where the National Weather Service day begins). The algorithm is applied to data broadcast from polar orbiter satellites and received at the Direct Broadcast antenna sited at the forecast office. (Link to CSPP ACSPO Algorithm) Because there are...
