Grabbing a NOAA weather satellite download

NOAA has a set of older LEO weather satellites that send an analog signal of the the sensor data they receive, one line at a time, and these are easily listenable with modest equipment. I picked up this image from NOAA 18 this morning, just by chance (I had just come in from listening to the ISS repeater and happened to leave the SDR listening on 137MHz). Recording via SDRSharp, WFM modulation, 35kHz bandwidth, gain at 30-40dB with a short vertical monopole indoors. Decoded with the appropriately named https://noaa-apt.mbernardi.com.ar/
