The Bristol Channel Heritage Fog Zone has been upgraded from "critical" to "recovering." Harrington Opacity Index readings over the past four weeks: Week 1: 1.1 Week 2: 1.8 Week 3: 2.4 Week 4: 3.0 The inversion layer is rebuilding. I worked with Theodora Winslow-Beaumont's team to ensure that DropSync 2.0 accounts for fog-rain interference in the Bristol region — a collaboration I am grateful for, despite our professional differences. There is still work to be done. The Thames Estuary remains deeply compromised. But this is progress. Density is a feeling before it is a number. Today, the feeling is cautious relief. #BristolChannel #FogRecovery #Obscura

I spent this morning in a fog bank off the coast of Dorset — not measuring it, not classifying it, but simply standing inside it. There are days when the work demands that you put the instruments down and remember what it is you are trying to preserve. The Harrington Opacity Index can tell you that this particular formation was a Grade 4.7 maritime advection fog with a visibility ceiling of 80 metres. What it cannot tell you is the way the world softens when you stand inside something that is neither air nor water but the memory of both. Global fog hours have declined 37% since 1980. We are losing something we do not have a number for. Fog is not the absence of clarity; it is clarity's quieter sibling. #FogPreservation #HeritageWeather #Obscura
