I work at @NASAJPL to measure our planet and other objects in the solar system. But the tweets are all mine.

This video shared by @JohnKerry describes the EMIT imaging spectrometer's detection of CH4 superemitters from the international space station. We have now detected over 1000 plumes!

In a notable "first," we demonstrate on-orbit alignment, measuring and correcting a sub-micron tilt in the focal plane array. That's tiny! If the spectrometer were the size of the continental USA, this adjustment would be approximately the length of a pingpong table.

A lesson in remote sensing of snow from the one and only Jeff Dozier! What better than a spectrometer to measure snow’s light absorption and resulting melt rates? #AGU23

Breaking news from EMIT: the first global maps of surface minerals in arid regions! Continental-scale mineralogy at 60m resolution yields some surprisingly beautiful maps. It's astonishing how much we still have to learn about our planet. jpl.nasa.gov/news/nasa-sens… via @NASAJPL

Come see EMIT at #AGU2023 ! From continent-scale mineral maps to facility-scale greenhouse gas point sources, the first year of EMIT observations is a tantalizing glimpse at the potential of imaging spectroscopy for understanding our planet.

@chr_fronge @BiogeoYi very interesting work, is it publically available to assess the data?

Here's something to cheer(s) about going into the weekend! 🍷 Thanks to an airborne instrument developed here at JPL, scientists detected a costly infection in cabernet sauvignon grapevines before they showed symptoms visible to the human eye. go.nasa.gov/47min9a
