One El Niño signal, three climate variables! September 2026 shows striking similarities to 2015 in CM SAF satellite records: more clouds and rainfall, but less solar radiation over the equatorial Pacific. A nice example of monitoring El Niño's atmospheric impacts. #ElNino #ENSO

$Three maps show September 2026 climate anomalies over the tropical Pacific from CM SAF satellite records: CLARA-A3 cloud fraction and surface solar radiation, and GIRAFE v1 precipitation. Along the equatorial Pacific, increased cloud cover coincides with reduced solar radiation and above-average rainfall. Opposite patterns are visible over parts of Indonesia and the surrounding region.$ $Three maps show September 2015 anomalies in cloud fraction, surface solar radiation and precipitation over the tropical Pacific. During the strong 2015/16 El Niño, increased cloudiness and rainfall coincided with reduced surface solar radiation along the equator. The spatial patterns closely resemble those observed in September 2026.$

How can satellite data support useful climate indicators? At a workshop hosted by SMHI, participants including CM SAF colleagues identified three priorities: combine data sources, start with user needs, and share methods to build sustained climate services.

CM SAF satellite data show that Switzerland averaged around 480 hours with land surface temperatures ≥27.8°C in summer 2026, which is over four times the 1991–2020 average. These are surface, not air temperatures. More in the MeteoSwiss blog linked below.

27.8°C marks the 95th percentile of hourly summer land surface temperatures across Switzerland in 1991–2020.
Colors show the number of hours per month at or above this threshold.
Land surface temperature is distinct from air temperature.

New CM SAF GEO-Ring data: cloud and top-of-atmosphere radiation products for 2021 are now available! Today at #EMSC2026: Jan Fokke Meirink presents the work. 🕚 11:45–12:00 · Session 2.A 📍 Room 2.02+2.03 www.cmsaf.eu/demo_isccpng

$Two maps from the CM SAF GEO-Ring ISCCP-NG Demonstrator showing cloud fraction and reflected solar radiation at the top of the atmosphere. Cloud fraction describes the proportion of an area covered by clouds; reflected solar radiation describes sunlight returned to space by the Earth–atmosphere system. The maps illustrate the near-global coverage obtained by combining observations from five geostationary satellites. The demonstrator dataset covers 2021.$

What can satellites tell us about Arctic climate change? Today at #EMSC2026: Abhay Devasthale on CLARA-A3, Arctic trends and sea-ice melt. 🕛 12:00–12:15 · Room 2.02+2.03 One of six CM SAF-related contributions across today’s Climate Data Records sessions 2.A and 2.C.

“A changing Arctic”: seasonal trends from the CM SAF CLARA-A3 climate data record. A grid of 32 Arctic maps has eight columns, April to November, and four rows: surface albedo, total top-of-atmosphere flux, reflected shortwave flux and outgoing longwave radiation. Blue indicates negative trends and red positive trends. Surface albedo and reflected shortwave radiation show widespread decreases during summer. Outgoing longwave radiation shows increases across much of the central Arctic in spring and autumn. Total top-of-atmosphere flux shows contrasting seasonal patterns, with predominantly negative trends in summer and positive trends in spring and autumn. Each row has its own colour scale. White areas cannot be interpreted without the original figure’s masking information.

Can neural networks help to retrieve cloud properties at night? Explore our ISCCP-NG GEO-Ring research at #EMSC2026. 📍 Today, 22 September | Tuesday Poster Session Spectrum B–C, Copernicium Poster 257 | Presented by Jan Fokke Meirink

Scientific poster: “Nighttime Retrieval of ISCCP-NG Cloud Optical and Microphysical Properties using Neural Networks” by Nikos Benas, Jan Fokke Meirink, Martin Stengel and Salomon Eliasson.

The study explores how neural networks can estimate cloud optical thickness and effective particle radius at night, when methods relying on reflected sunlight are unavailable. It uses CM SAF’s ISCCP-NG GEO-Ring demonstration dataset, covering 2021 at 30-minute intervals.

An initial multilayer perceptron is trained using daytime infrared brightness temperatures and corresponding cloud retrievals. It produces meaningful results but lacks spatial and temporal context, serving as a baseline for further development. Computations use the European Weather Cloud; future evaluation will include independent observations from active sensors.
