3/ RTN seems prepared for the worst: Commander-in-Chief of the Royal Thai Navy ordered various units of the Navy to help.
First cloud-free #Sentinel2 satellite images in a month dropped yesterday. Great to check out snow levels, reservoirs, and wet wet wet in the Butte Basin/Lower Sacramento River. First image compares Colusa area now vs 12/15/2022. #Geography #RemoteSensing #CaWx #CaStorm 1/x 
Imagery paints a picture of soil types. Along the River, coarser soils settle quickly once floodwaters slow down. Blue areas have more clay, because super-fine soil particles can stay suspended longer, travel farther in slow-moving floodwaters. Orchards prefer coarse soils. 2/x
Plumes of sediment from the Pajaro and Salinas Rivers are still very visible in the Monterey Bay on 1/19/2023. Two visualizations of sediment in the lower Delta and San Pablo Bay. 3/x

It's harvest season in Southern Ukraine🇺🇦 but agricultural activity has largely halted in areas most affected by the fighting.
The impact is so severe that it can be clearly seen from space🛰️ Can you spot it?

Recently harvested fields are seen in light brown in this #Sentinel2 image from Kherson region;
a distinctly darker belt is seen around the line of contact, where harvesting has been impossible.

This is what it looks like up close.
Large swaths of crops have also burned as a result of artillery fire.

Hé les @decodeurs c'est super d'utiliser #Sentinel2 mais attention il n'y a pas d'image prise le 21 juillet... lemonde.fr/les-decodeurs/…
L'image que vous avez utilisée date du 17 juillet alors que le feu n'avait pas atteint sa surface max. apps.sentinel-hub.com/sentinel-playg…
En attendant l'image Sentinel-2 d'aujourd'hui, Il y a une image plus récente prise par Landsat le 19/07 qui montre que la surface a largement progressé depuis le 17/07 malgré les nuages
It is visually confirmed that something is burning in #Kherson. It is currently rumored that #Ukraine Armed Forces lead an assault against the Airport. So I looked into it a little bit.
Taking a look at #Sentinel2 imagery, the latest flyover from the constellation was at 8:57 GMT. There is a concentration of what appear to be helicopters on the apron, along with pit marks from previous MLRS strikes.
With fire evidently present, utilizing #FIRMS. The first indications of fire were detected at 10:51 GMT. With the fire of the greatest brightness correlating concentration of helis on the apron.
🌋A wonderful illustration that will now need some updating

Quand #Panama bloque #Suez : le porte-conteneurs #EVERGIVEN bloqué au sud du Canal de Suez, vu par le satellite #Sentinel2 le 24 mars. Première leçon : faire demi-tour dans un canal de 300m de large n'est pas l'idée du siècle quand on mesure 400m... #Copernicus #EarthObservation
Mise en service en 2018, #EVERGIVEN est un gros navire, un des plus gros porte-conteneurs : 400 mètres de longueur et 220000 GT (drôle d'unité) de tonnage. Il appartient à la société taïwanaise Evergreen Marine et bat pavillon panaméen. Photo Kees Torn #Suez
L'accident du porte-conteneurs #EVERGIVEN s'est produit le 23 mars au matin, bloquant la totalité du trafic du canal de #Suez. Les données #AIS montrent que ça se bouscule au portillon. Pour fixer les idées, une vue globale du canal de Suez. Image #Sentinel2 du 24/03 #Copernicus

A friend of mine (@hazeldickens) recently asked @HayleyEversKing and I; “Can you see the #Jacaranda trees, which bloom every year in #Pretoria, from space?”…#thread (1/n)
For those that have never seen them; #Jacarandas grow all over #Pretoria & #Johannesburg & each year explode in an incredible purple display between September & November. We saw these when we visited @UPTuks in 2011, on an @Access_HP course & they are stunning! (2/n)
We’re not land remote sensing aficionados (ocean please!), but decided to have a look using @CopernicusEU @ESA_EO #Sentinel2 data. We started by comparing a time of year when we know the trees are in bloom (now), with one where we know that weren’t (July) (3/n)
