). Overleaf are a series of plots showing the Gerrity Skill Score in relation to the agreed performance measure for forecast Cloud Base and Visibility at airports in receipt of 9, 24 and 30 hr TAFs. The values obtained range from 0 to 1, where 1 indicates perfect forecasts every time, the value we aspire

Areas of expertise Satellite imagery. Volcanic cloud detection and retrieval. Current activities Cameron's work aims to enhance the use of existing and new satellite radiance observations to improve the tracking of hazardous volcanic clouds. Volcanic clouds are hazardous to aircraft and satellites

Nina is a scientist working with modelling the dispersion of volcanic eruption clouds using the Met Office's atmospheric dispersion model NAME.

Areas of expertise Nina has been working with Lagrangian Particle Dispersion Models and inversion modelling since 2008 with a main focus on forecasting volcanic eruption clouds. Her key areas of expertise include: dispersion modelling (FLEXPART and NAME) inverse modelling   volcanic eruption clouds

widely from late morning onwards. After another bright, cold start on the 2nd, with isolated showers over northern counties and locally along the south coast, cloud increased by midday with showers occurring quite widely. All areas were cloudy and windy on the 3rd, with rain already in the west

image is the amount of the UK without cloud cover. There is unbroken sunshine across much of the UK. You can also see smooth edged cloud on the coast of East Anglia and to the west of Scotland. This is low cloud called stratus, a typical cloud formation that occurs where moist air at low altitudes

who adopt a more conservative approach. Unlike the SQI more than one category threshold is used by the GSS (see table 1). The Met Office assess all the TAF cloud base and visibility categories defined by ICAO. At the time of writing, the following categories are used for TAF assessment: Surface
