On Diwali night, many of Delhi’s pollution monitors stopped reporting PM2.5 just as readings neared 1,000. At 1am, only 13 of 39 were sending it, though they kept sending other readings. Last year, 29 of the same monitors recorded more than 1,000. @htTweets #Diwali

And because they didn’t register the worst, and the AQI measure is a 24 hour average, the overall reading will remain below 400. Classic bureaucratese — manage the measure, not the problem. And all will be well.

Yes. The NASA one. And also points out that this is an undercount by a factor because burning has moved to later in the day .

My colleague @VinayakD has put together a really cool (and representative) dashboard for Delhi’s bad air. It is comprehensive and scrapes data from multiple sources to understand meteorological conditions and source of pollution. hindustantimes.com/breathe

Super stoked to sight the Eurasian Hobby at #VetalTekdi today. A passage migrant over the city on its way to wintering grounds in Africa.

Nothing beats running in the rain (Parker was right) as long as you have a trusted zip pouch!

I am so sorry for making those jokes about Delhi Traffic Police. Very insensitive of me to speak ill of an extinct species.

Parents gave their kids these double and triple AAA names so that their name would be first in the class register. I remember, my son’s class had more kids with names starting with As than any other letter.

Delhi's latest traffic gridlock is physics.
@VinayakD explains here
Delhi's drivers, unfortunately for all of us, mostly drive like what physics calls Brownian motion, which makes it even worse
