Rain accumulation: Total rain accumulation in the next hours or days. It's being deduced from the reference time (see 'About these data' section in the Quick Settings Menu).

Ohh ! not again!

Mauna Loa Observatory measured 415.79 parts per million of CO2 in the atmosphere on January 21, the highest ever daily average.

The UK's Met Office forecasts that the annual average CO2 concentration at Mauna Loa will be 414.2 ± 0.6 ppm. For the first time, monthly CO2 levels will exceed 415 ppm (during spring and summer) and will remain above 410 ppm for the entire year. Forecast monthly mean CO2 will peak at 417.4 ppm in May.

The Met Office forecasts that, at global level, the annual rise in CO2 concentration is expected to be relatively large and similar to last year's due to 2020 due to emissions from fossil fuel burning, land use change and cement production and a continuation of the temporary weakening of the land carbon sink.

This accelerates this year's annual CO2 rise by about 10%, with between 1% and 2% due to 2019/20 Australian bushfires.

2019 was an eventful year for global weather - see how some of the more severe storms looked from space in this brand new "Year of Weather" video from EUMESAT.

This visualisation, comprised of imagery from the geostationary satellites of EUMETSAT, NOAA, the CMA and JMA, combined with data from EUMETSAT's polar orbiting Metop satellites, shows an entire year of weather across the globe throughout 2019.

This ultra-high resolution (4k) visualisation has been produced by EUMETSAT's data visualisation team and is composed of a satellite infrared data layer, provided by MeteoFrance, superimposed over NASA's 'Blue Marble Next Generation' ground maps, which change with the seasons.

@TZ
Thanks a lot!

... Alternatively
I think it would be a great idea to customize the color scale for INFRA.
