WEBVTT FILE 1 00:00:02.490 --> 00:00:07.710 Ground level ozone, it physically burns your lungs. NO2 2 00:00:07.740 --> 00:00:15.000 is a toxic gas. It is linked with pediatric asthma. PM2.5, 3 00:00:15.030 --> 00:00:18.210 the small particles you breathe in, they're small enough that 4 00:00:18.210 --> 00:00:23.280 they can go through your lungs into your bloodstream. One of 5 00:00:23.280 --> 00:00:25.980 the exciting things about this AEROMMA STAQS field campaign is 6 00:00:25.980 --> 00:00:28.590 it's going to help us calibrate and validate the TEMPO 7 00:00:28.590 --> 00:00:35.400 satellite. So while we're flying, both the remote sensing 8 00:00:35.430 --> 00:00:37.860 and the sensors that are measuring what's in the 9 00:00:37.860 --> 00:00:41.220 atmosphere down low, TEMPO is scanning overhead, and so we're 10 00:00:41.220 --> 00:00:45.030 going to use that data to help improve the precision and 11 00:00:45.030 --> 00:00:46.830 accuracy of the TEMPO satellite.
