Huge subset of issue #274 19 years of data; each of the 19 folders contains around `150 GB, so about 2.8 TB total.

following description from https://www.ncdc.noaa.gov/cdr/fundamental/amsu-bmhs-brightness-temperature

This dataset provides advanced scientific researchers a high quality Climate Data Record (CDR) of global Brightness Temperatures.

Instrumentation utilized is the NOAA Climate Data Record (CDR) of Advanced Microwave Sounding Unit-B (AMSU-B) and Microwave Humidity Sounder (MHS) brightness temperature (Tb) in "window channels" and "water vapor" channels. The data period of record begins in 1998 with monthly updates. The data resolution is roughly at 16 km over the entire globe, with 90 observations per scan. Channels utilized are 89, 150, 157, 183 +/- 1, 183 +/- 3, 183 +/- 7, 190 GHz. The AMSU-B sensor is part of instrumentation suites on NOAA-15, -16, and -17 satellites. The MHS sensor is part of instrumentation suites on NOAA-18, -19 and MetOp-A satellites. To improve data accuracy, visual inspections and verification of the various corrections are applied. The CDR is useful as input to hydrological products to derive global precipitation, ice water, snow cover, and snow water equivalent.

I'm going to start grabbing the files and uploading them to an unlimited google drive. I will start from 1998 and work up if anyone wants to start from 2017 and work down.

I'm also taking a stab at it - will start from 2017.
