Climate models need clouds in 3D: EarthCARE’s view of a hurricane shows us why - Earth Online Thanks to EarthCARE’s vivid observations of a hurricane eye wall, we can better see how clouds reflect and trap heat not just from their top and bottom, but from their sides as well.

The eye of Hurricane Humberto, observed last September by #EarthCARE, provides a great example of 3D radiative effects that are currently missing from climate models - see the latest EarthCARE Image of the Month: earth.esa.int/eogateway/su...

Marvellous performance of Malcolm Arnold's spine-tingling Fifth Symphony by the Junior Guildhall Symphony Orchestra last night - a masterpiece that's rarely performed in concert so I'm very happy to have seen it live.

...and yesterday at 14.28 UTC. EarthCARE cannot penetrate thick clouds of course (shown in grey, leading to some gaps in EarthCARE aerosol optical depth) but this is an excellent demonstration of the potential to use EarthCARE to evaluate and improve our aerosol forecasts. (2/3)

Green party wins Gorton and Denton byelection, pushing Labour to third place in blow to Keir Starmer Hannah Spencer elected as party’s first MP in northern England, as Labour sees a 25.3% drop in vote compared to 2024

Great result for progressive politics in the UK. If the first law of politics is "learn to count" (LBJ), the 2nd has to be "don't abandon your base". Labour's response to the far-right threat has been to lurch to the right - who'd have guessed this wouldn't work? www.theguardian.com/politics/202...

I'm currently writing up a paper in which we used FAAM underflights of EarthCARE to evaluate and refine its retrievals of cloud properties and updrafts, crucial to building trust in EarthCARE's global measurements of clouds and their impact on climate. This is a bad day for UK science. (2/2)

Crazy to axe the world-class FAAM aircraft - a big blow to observational atmospheric research in the UK. I've used data from the Hercules and then its successor the FAAM since starting my PhD in 1995 - there's no substitute for getting right inside a cloud to find out what's really going on! (1/2)

The left column shows various EarthCARE measurements of a deep nimbostratus cloud over Ontario. The right column shows comparisons between EarthCARE’s estimates and in situ aircraft measurements. The bottom two rows confirm that the terminal fall speed of snowflakes is fairly constant whereas the vertical motion of the air fluctuates rapidly and can be estimated well from EarthCARE, the first time this has been possible from space.

There have now been 100 aircraft under-flights of #EarthCARE, each providing invaluable information to calibrate and validate the data products. This example shows very good agreement between EarthCARE and aircraft vertical air motion in nimbostratus. Full article here: earth.esa.int/eogateway/su...

Here is the wider context: satellite observations on the left and the two model versions on the right, visible imagery on top and thermal infrared on the bottom. The eye is stubbornly too wide in the model: what should we change in the model to improve this?

Doppler velocity (positive up) through Hurricane Humberto: top is EarthCARE, middle is the ECMWF 9-km model and bottom is the ECMWF 4.4-km model.

Never before have we been able to measure vertical velocities from space: on the top is EarthCARE showing falling rain and snow (blue) but in the eye-wall the cloud particles are lofted up (red). The next two panels show the 9- and 4.4-km models with the 4.4-km starting to capture the updrafts!
