GOES-16/17 2019 Virtual Science Fair


Frequently asked Questions - and answers.

Where can I get real-time GOES-16 (GOES East) data?
Lots of places! But we reccomend this site from the UW-Madison: https://www.aos.wisc.edu/weather/wx_obs/GOES16.html

Where can I get real-time GOES-17 (GOES West) data?
Lots of places! But we reccomend this site from the UW-Madison: https://www.aos.wisc.edu/weather/wx_obs/GOES17.html

What time range should the GOES data be from?
For GOES-16, anytime after June 1st 2017 and for GOES-17 after mid-December (to be refined) 2018.

What areas can we investigate?
Any area that GOES-16 (or -17) can observe, which covers North and South America and the surrounding oceans.

Where do we access historical (non- real-time) GOES-16 data files?
https://cimss.ssec.wisc.edu/goes/goesdata.html#data shows that recent files can be accessed from the cloud, while older files (weeks to months) via NOAA's CLASS (Comprehensive Large Array-data Stewardship System).

What files should we access for ABI data?
While the "radiance" files could be used, the most useful might be the Cloud and Moisture imagery (CMI) file that contain reflectance factor values for the Advanced Baseline Imager (ABI) bands 1-6 and brightness temperature for ABI bands 7-16.

How does one decode a ABI CMI file name?
OR_ABI-L2-CMIPC-M3C02_G16_s20182831802203_e20182831804576_c20182831805093.nc means it was produced operationally, ABI sensor, Level-2 (derived product), Cloud and Moisture imagery product; Conus sector, Scan Mode 3, Channel 2, GOES-16, image start in the year 2018, ordinal date of the year of 283, 18:02.203 UTC and the end and central image times for this netCDF.

What's an ordinal date?
The sequential day of the year, for example, Oct 12, 2018 is 285.

Where can I find out more about the ABI and it's band uses? What's each ABI scan mode?
Lots of info out there!

What spectral bands are on the ABI?

What are the 3 domains scanned by the ABI?
Full disk, Contiguous US (CONUS) and smaller meso-scale sectors.
See examples in this scanning domains in this animation.
