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?

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!

The paper describing the synergy retrievals is here: amt.copernicus.org/articles/16/...
A unified synergistic retrieval of clouds, aerosols, and precipitation from EarthCARE: the ACM-CAP product
Abstract. ACM-CAP provides a synergistic best-estimate retrieval of all clouds, aerosols, and precipitation detected by the atmospheric lidar (ATLID), cloud-profiling radar (CPR), and multi-spectral i...

Nice paper, thanks! ECMWF web article coming soon comparing our observations of Humberto with simulations by the IFS at high resolution.

There are some tools listed at the page below. This image was produced by Shannon Mason using his free ectools package but I would like these to be produced routinely for all EarthCARE frames. www.earthcarescience.net/tools

Second, the signal from the "Rayleigh" channel of EarthCARE's lidar is strongly related with ocean chlorophyll estimates from routine ocean colour measurements, with the advantage that EarthCARE's lidar can continue to make measurements in polar night!

First, the depolarisation of the land surface measured by EarthCARE's lidar seems to be very well correlated to the widely used "NDVI" vegetation index - but why? We don't yet know but potentially this could be telling us something new about vegetation!

And here's EarthCARE's radar reflectivity with GOES-E for context (thanks to Mark Fielding)!

In addition to the scientific insights we can gain from EarthCARE's precise measurements, the satellite is an inexhaustible source of beautiful imagery.
