VIIRS aerosol optical depth (AOD) from @JPSSProgram satellites observed thick wintertime smoke & haze (AOD >1, dark red shading) mixed with clouds (missing AOD, grey shading) across South Asia today 24 Dec. @NOAASatellites @falgunipatadia @pawanpgupta

Today 31 Oct is 1st day of #Diwali! Celebrations can exacerbate wintertime #haze in #SouthAsia. @JPSSProgram #VIIRS aerosol optical depth shows widespread thick haze (dark red) but conditions along much of #IndoGangeticPlain clearer than recent years. @pawanpgupta @falgunipatadia

According to @OpenAQ 39% of all countries & territories don't have access to regularly updated #AirQuality information. See how we're partnering to close that gap 🌫️ https://t.co/Wv0jElkkI9

Stubble burning 🌾🔥has begun in North India. Punjab & Haryana shows 127 firecounts between Sept 19-24. PU-PGI team will keep you updated. Neighboring country #CRB also adds to pollutant load. All stakeholders must collaborate to curb air pollution. #AirQuality #StubbleBurning

Yesterday marked the #AutumnEquinox, signaling the official start of astronomical #fall in the Northern Hemisphere! Over the past year, we've gathered a daily image from @NOAA's #GOESEast 🛰️, taken at the same time each day. Together, they show the sun's angle shift over time

A @NASA & @StateDept partnership is making air quality forecasts available for the roughly 270 U.S. diplomatic posts globally. Using NASA satellite data & computer models, the ZephAir tool now provides three-day forecasts for hazardous PM2.5 air pollution. https://t.co/tafKOxoDtb

@AguGeohealth NASA’s MAIA mission will use satellite data to study how air pollution affects human health! Use this interactive tool to learn about MAIA target areas, explore their geospatial characteristics, and access ground PM2.5 and PM10 data from these regions

This is a brilliant idea for a creative outreach tool from the folks at @NASAEarth to spell your name with images from the Landsat missions. I love mine on 🛰️ images, go try yours here. Happy weekend! https://t.co/RkMJ8qEBVK
