Bringing you a whole new perspective of our Earth on September 14th 2020
High resolution views of forest structure and #wildfire hazard via the @forestobs
@SaloSciences and @planetlabs built this platform to provide free data to scientists and the public

You can now access precise forest carbon data in just a few clicks on SkyFi – with clear, transparent pricing.
@Planet's Forest Carbon Measurements provide reliable global data on how much carbon trees store. It uses satellite imagery, radar, and LiDAR sensors, which measure tree height and forest thickness around the world. Advanced computer models trained on real forest measurements accurately estimate carbon storage without needing ground visits.
Planet verified these results against respected datasets from NASA, ESA, and the United Nations. This validation shows clearly where the data performs best, highlighting accuracy and areas needing caution.
Businesses, researchers, and governments can use this data to monitor forest health, meet environmental rules, manage land sustainably, or track forest changes anywhere globally.
Start analyzing forest carbon today – order your data easily through SkyFi’s user-friendly platform

🌲 New: Planet’s Forest Carbon Analytics are now on SkyFi.🚀 Link in 🧵 and this is another step increasing our relationship with @planet 🌎
This tool measures forest health and carbon storage worldwide. It’s precise, simple, and efficient.
Planet’s expertise in satellite imagery makes this a powerful addition to our @SkyfiApp toolkit. Users can now track forest changes and carbon levels with greater accuracy, supporting conservation and climate efforts.

The Hughes Fire rapidly surpassed 10,000 acres north of Santa Clarita in LA County this week. It is currently 56% contained, according to Cal Fire, and the Santa Ana winds are expected to ease today. Tanager-1 captured the extent of its burn scar in infrared data, with SkySat and PlanetScope supplying additional details.

Here we go again. Another round of very strong & locally damaging offshore winds is imminent across SoCal. Due to now record-dry vegetation, this will result in another "extremely critical" wildfire risk period, esp. across parts of LA & Ventura counties Mon-Tue. #CAwx #CAfire

This remarkable remote camera footage from the peak of the #EatonFire as it roared through Altadena amid winds gusting 70-90 mph illustrates just what this was: a true firestorm, a literal blizzard of embers. The reality on the ground really *was* that extreme. #CAfire #CAwx

Another tough reality: in urban firestorm of this magnitude, municipal water systems simply aren't designed to keep up.
It *is* possible to build redundant emergency firefighting water system (SF has one, a legacy of 1906 quake & fire), but few places do. sfpuc.gov/about-us/our-syste…

Regarding not having enough water to fight the SoCal fires; here is some water usage numbers from someone who knows a lot more about urban firefighting than I do.

I spent two hours yesterday in conversation with Anderson Cooper's team; portions of this conversation will appear in this hour-long CNN special on the Los Angeles wildfire disasters running on Sunday evening. #PalisadesFire #EatonFire #LAfires #CAfire cnnpressroom.blogs.cnn.com/2…

This is a significant, & somewhat unexpected development. UCLA campus remains outside of any evacuation orders or warning, but is now much closer than before. Personally, I highly doubt this fire will make it to the east of the 405, but the situation remains fluid. #CAfire [2/2]
Maxar just out there casually snapping pics of rotor water drops from low earth orbit 😳
The satellite image of @Maxar also captured a firefighter helicopter dropping water on hot spots north of Altadena. Location: 34.226, -118.117.
A bit of good news for Pacific Palisades, while much of the city was decimated, there appears to be a few pockets that received relatively little damage. See the figure below for a combined hi-res @planet optical and @umbraspace SAR look

I continue to be floored by the skill, fearlessness, and tenacity of the air attack pilots working these fires
They and their hundreds of counterparts working the ground are superhuman to face down situations like this

Incident Command for the #KennethFire has requested 250 additional engines, 40 crews, and 20 dozers from Los Angeles and Ventura Counties

Major caveat: this imagery is tentative and informal; not all structures within the fire footprints have burned. But this imagery suggests that there are 10,000+ potentially affected structures within *each* fire footprint (which have expanded since yesterday). #LAfires #CAfire

As enormous scope of the damage from #PalisadeFire & #EatonFire becomes clearer, I wanted to share this imagery depicting fire footprints (from 1/8) & potentially affected structures within them (provided by my colleague David Marvin @ Planet Labs). [Image below] #LAfires #CAfire
