SC 12 - Making a case study by Training @EUMETSAT

Cold advection over Central Europe

TrainingEUMETSAT — 2021-03-16 09:58:27 UTC

Cold air is still being advected to Central Europe and Mediterranean. Violet colour in Airmass RGB suggests cold airmass.

We can check in the e-port (eumetrain.org) what the model fields look like, compare the location of the violet area in satellite image with the temperatures....

Its onset, the difference between other years in the same regien and relevance to other Karenia spp. algal blooms. Definitely will use OLCI, but also other tools most probably. The example below is from Copernicus-GlobColour product of dinophytes change, in which Karenia spp. is also classified.

Siberian 2019-2020 wildfire seasons

agbbruno90 — 2021-03-22 15:22:16 UTC

During last decades northern hemisphere is observing a large enhancement in wildifire number, duration and intensity. During 2019 summer period an unprecedent wildfire activity was recorded. The biomass burning emission was transported on hemispheric scale as observed in the attached animation of CO measured by AIRS instrument onboard on Aqua satellite.

The measurements of interest could be: Visible images, CO total column, Aerosol Index, Thermal anomalies, false color images from corrected reflectance to detect fire impact on vegetation, night imagery

The instruments to use could be: OMPS, AIRS, VIIRS, TROPOMI, CALIOP

The satellites to consider could be: Suomi NPP, Aqua/Terra, CALIPSO, Sentinel satellites

Another interesting approach could be to compare the atmospheric impact of wildfires in Siberia with the wildfires whxich afflict Amazon during almost the same period.or the fires in Australia

Day of Fire in the Amazon

jufonsoa — 2021-03-23 22:04:03 UTC

Day of fire, 10 August 2019, was a day of criminal fires in the south edge of Amazon forest, provded by farmers in the region. The action was indirectly supported by Brazilian governance, marking one of the darkest day about environemtal conservation in the country.

Correlate with Carbon monoxide, Aerosol Index, thermal anomalies and Sulfur dioxide.

On August 3-4, 2019, the weather in the Odessa region was determined by the "southern" cyclone. Extraordinary rain was observed on the Belgorod-Dniester MS - 121 mm in 6 hours

impact of vulcanism on marine ecosystems

asindic — 2021-03-24 08:26:58 UTC

Examine the impact of vulcanism on marine ecosystems

The Kilauea volcano is one of the most active volcanos would be a suitable candidate for the study. There are continuous eruptions from the 1980s onwards, with a massive outbreak in 2018.

Possible questions of the case study could be:

Can we detect the sulfur dioxide plume and lava stream and correlate that with events such as

regional ocean heatwaves
algae bloom
upwelling
acidification

Instruments/products

Sentinel2/3, CMEMS global products (resolution may be too low?)

Transverse bands over the central interior of South Africa - 8 March 2021

elaniclaassen — 2021-03-24 10:36:01 UTC

Transverse bands are an indication of moderate turbulence usually located high up in the atmosphere. It is important to constantly monitor the satellite images for signatures that can influence the aviation industry. Turbulence can be classified as light, moderate, severe or even extreme and can lead to uncomfortable passengers, injuries or in extreme cases even casualties.

Heavy to very heavy rainfall at Dibrugarh, Assam (India)

tlhouvumimd — 2021-03-24 12:47:13 UTC

On 22-25 June 2020, there was heavy to very heavy rainfall in Upper Assam with the Meteorological Office, Mohanbari recording 38.7mm, 49.8mm, 75.2mm and 116mm over the four days respectively leading to wide spread water logging in Dibrugarh Town which is 15km from the observatory. The worldview has also shown a good satellite view.

Where did the dust storm disappear????? Case Study

2025-05-15 09:16:11 UTC

The controversy arose over the dust storm predicted by the Egyptian Meteorological Authority on April 30, 2025, which some considered an April Fool's joke, and many questioned where the storm was, claiming that the Egyptian Meteorological authority deceived us!!!!!

The Arab Republic of Egypt was affected by a khamsin low-pressure system starting Tuesday, April 29, 2025, that began forming over the eastern desert of Libya due to rising temperatures, with atmospheric pressure reaching 1000 mb. This was accompanied by high wind speeds reaching 80 km/h and gusts, which stirred up sand and dust over the eastern Libyan Desert, gradually advancing to the western Egyptian border. The storm extended to Siwa, where wind speeds recorded 39 knots, approximately equivalent to 72 km/h, significantly reducing horizontal visibility to 500 meters.

As the khamsin low-pressure system progressed on Wednesday, April 30, its effects continued over the western desert and then gradually moved inland to include cities in northern Upper Egypt, Greater Cairo, the canal cities, and then cities in southern Upper Egypt and Sinai.

Numerous weather predictions and warnings were issued by the forecasting and early warning center of EMA, and the low-pressure system was monitored hourly using various global and local numerical models, as well as through monitoring the movement of third-generation satellite images and recording from observation weather stations continuously.
