I developed a tutorial on Google Colab for using #Python (esp. @xarray_dev) for geospatial / climate data analysis🧵 1️⃣/5

📢 I’ve started a new newsletter–GeoAI Unpacked–to share deep dives and insightful analyses on AI & geospatial / climate-tech industry.

🛰️ For the 1st issue, I've explored EO foundation models. Check it out and subscribe to stay tuned:

@cherian_deepak Fantastic! 👏👏

[Ali Ahmadalipour @hydroclimali]

@KellyHereid @geosmx Thanks for the shout out :) Much appreciated! Lots of opportunities now available at the intersection of climate, insurance, and AI.

@Keiko_geo The article implies financial reasons for the layoff. Yet they had hired scientists even two months ago (who are now laid off). Maybe they were in the midst of fundraising and things didn’t go as planned? Still, not cool to join and let go a few weeks afterwards 😐

I've also shared the code to generate high quality plots using Cartopy:
+ Visualize in a desired geographic projection
+ Add features like state boundaries
+ Customize the colorbar

I’ve developed a new #python tutorial that combines the power of Google Earth Engine and @xarray_dev for geospatial data analysis. The combo seems really powerful and convenient to use!

The combination of GEE and Xarray seems to make your typical geospatial modeling workflow more convenient.

@aravindEO @mouthofmorrison Sorry to hear about the layoffs. Happy to help (and possibly refer) those who are impacted. Planet has hired a lot of top notch talents over the past years.

[Ali Ahmadalipour @hydroclimali]

@philippemiron Great decision of course. And thanks for the shout out :)

[Ali Ahmadalipour @hydroclimali]

@safeeqkhan @PatrickTBrown31 Ah of course, it’s monthly avg not annual. My bad. Thanks for clarifying.

3 weeks of California storms visualized in 30sec. ~30 trillion gallons of water! I shared a few points about the event here: https://t.co/BCiVhqJgg4
Data: MRMS (by NOAA) on AWS S3 (hourly, 1km spatial resolution)
Tools: Python (mainly xarray & cartopy)

[Ali Ahmadalipour @hydroclimali]

@jamiecmonty Wonderful, thank you! :)

I've been sharing a newsletter focused on technical & data science jobs in geospatial (i.e. 🌧climate-tech, 🌽ag-tech, 🌊risk modeling, ⚡️energy, 🛰remote sensing, & ♻️sustainability).
If that sounds interesting, check it out & I hope you find it helpful: https://t.co/XOH9I1MaPX

Here's my conversation with Abbas Amanat, a historian at Yale specializing in the modern history of Iran. We talk about the Iran protests, the death of Mahsa Amini, abuses of power, nuclear weapons, and the history & future of Iran and the Middle East. https://t.co/lder9TW90t

[Ali Ahmadalipour @hydroclimali]

@melliott_water It's a shame that many of our Iranian-American faculty (& students) have been silent & ignorant in the public & on social media (not even liking any posts about #IranProtests2020). Thank you Mark for being our voice! ❤️👏👏

Career update: This Monday was my first day at Google[X] @Theteamatx. I'm super excited to work on ML & geospatial applications for environmental extreme events. Climate change has been an integral part of my career & I'm glad to now work on it in a highly technical environment🚀

[Ali Ahmadalipour @hydroclimali]

I was interviewed by @BusinessInsider to elaborate on my experience in the climate-tech industry. Here's a summary of my conversation: https://t.co/MLVEIzp9Xc

Worth mention: Get comfortable w/ rejections. If you’re not being rejected, you’re not pushing beyond your comfort zone.

@benatoms This article explains some issues of CAT models: https://t.co/jxu1KrAi4O
Several startups are working w/ insurance & financial institutes, partly due to the shortcomings of CAT models (though GCMs are problematic too). Thus I'd say there should be a market for "better" data.

[Ali Ahmadalipour @hydroclimali]

@benatoms I think RMS has some info about CAT modeling: https://t.co/jYmNfF3TPj
I suggest you to take a look at these too:
1. Cat models and climate risk models: friends or foes? https://t.co/mwt2W0xJMs
2. Why climate models struggle with acute physical risks: https://t.co/lVpWAy5pOi
