Must-Follow Twitter Feeds for Earth Observation

Is Earth observation data useful when it comes in messages limited to 140 characters? Hundreds of organizations apparently think so. Here’s a list of essential EO Twitter streams to follow.

Earth observation (EO) data comes from all over and in countless forms: from satellites orbiting hundreds of miles above our planet, from marine buoys riding currents in every ocean basin, and from seismic sensors deep within the Earth. This cornucopia of data is shared at conferences, viewed online via an ever-growing number of portals, and on Twitter.

Yes, Twitter: the social media app known for vapid communiquÌ©s about comestibles and pithy life lessons limited to 140 characters per ‰ÛÏtweet.‰Û

But Twitter is also serious business, including thousands of accounts churning out data on every aspect of Earth observation.

Use of the app has grown tremendously since co-founder Jack Dorsey sat at a keyboard nearly seven years ago and typed the message ‰ÛÏinviting coworkers. jack.‰Û According to Twitter, there are now about 1 billion registered users, who have sent a total of 300 billion tweets since March 21, 2006.

Only 100 million users tweet on any given day, but that still translates into a huge amount of usable Earth observation data, especially if you know whose tweets to follow. And that’s the rub. Who do you follow to separate the EO signals from the noise of the Twitterverse?

To help users get started, I’ve put together a list of some of my personal favorite EO accounts grouped by topic below. Feel free to suggest others and we’ll add them to our Twitter feed @Earthzine.

National and International Programs

To my mind, the Twitter feeds below include some of the most important ones to follow for EO information around the globe. And this is just a small sample of what’s out there. (Several invaluable NASA and other twitter feeds are listed separately, below.)
