Just wanted to plug my data story on villages in Kerala and how hot they get. 



Was thinking of using Google Earth Engine for this story, but decided to go with Planetary Computer since it's Python-centric and I'm more familiar with that language.

Pretty sure earth/environment science guys won't be happy with my methodology, but hopefully there's enough of a logic to it to accept the story as a basic analysis.

Thanks! -shijith

Awesome stuff! Can it be extended to all Panchayats in the country easily?

Just a nitpick: why not use "median" as an averaging strategy? 

best,

Thanks for the comments Dilawar! To answer your questions:

I guess so, just have a feeling that services like Planetary Computer might not be able to handle all the data and could crash if you don't code it in a certain way. Planetary Computer allows you to create something called dask clusters to 'perform computation in parallel and at scale'. I'm an amateur coder, so I don't how to do all that magic, think you need to do all that for operations to complete without crashing.

Just a nitpick: why not use "median" as an averaging strategy? 

No strong reason really, i'm just thinking that since this is a story about how hot villages get, about temperature extremes, you need a measure of central tendency like average that takes in ALL values, instead of a measure like median that ignores extreme values.

Hi Shijith,

Really good work putting so many things together, this can be a good reference material for how to fetch and use data from these various sources. Many different technologies / techniques brought together here.
