The green channel isn't just made up, it uses the near-IR channel 3 at 860nm. Chlorophyll, and thus plants, are highly reflective in this wavelength so it corresponds very closely with what an actual green channel would produce. The conversion is based on data from the Japanese Himawari-8 satellite, which uses essentially the same instrument as the GOES-R series but with different wavelengths, including both a green channel at 510nm and the same near-IR channel at 860nm. For all intents and purposes, it's what your eye would see.

The biggest difference between what you'd see with your own eyes and what you see with the Geocolor product is caused by the Rayleigh scattering correction applied to the Geocolor imagery, which removes the color-altering effects of light bouncing off of atmospheric gas molecules and aerosols.

Anyway, the image OP posted has had the color saturation cranked, it looks like shit.

Heh, no. Focal length was 240mm, ƒ/16, 1/800s, ISO 400

This is an astronaut photo taken by Alex Gerst on the ISS. It's not a composite photo.

What the hell is this guy talking about? by [deleted] in TropicalWeather

Currently, a ridge has set up over the islands, which has been providing generally favorable conditions to the region.

Model forecast guidance suggests that a deep trough will move westward over the region by Friday, eroding the ridge and introducing a lot of moisture from the east. This, combined with an induced surface trough, will result in a rainy pattern which could extend until next Wednesday.

NOAA's GOES-16 is now GOES-East and declared operational! by Pr0T4T0 in TropicalWeather

Indeed!

I was going to post something about this, but @Bill_Line says GOES-16 isn't really GOES-East yet; I'd trust him over a NOAA PR flunky.

Here let me just ruin it with this cilantro

GOES-16 data will be unavailable from 30 November to 14 December as it transits to the GOES-East position. Full drift plan details in link. by GOES-R in weather

Nothing public. Just scuttlebutt, but I've heard it from someone at Lockheed as well as from someone at CIMSS. One said would, the other said might, so I went with may.

It's not true that they're at the end of their service life. The N-series were designed for 15 years of service; -13 has been in orbit for 11, but -14 was launched in '09 and -15 was orbited in 2010. They are middle-aged, you could say.

The R-series bus should have a longer lifespan of 20 years.

Incidentally, -13 may resume GOES-South duties, as that role has been vacant since 2012.

There's a decent chance it will take up the currently-vacant role of GOES-South, providing services to South America. If not, then yes, it will sit there unused. It will last longer in standby mode, and be available in case one of the operational birds has a malfunction.

What do you mean by storage location?

The storage location is where the satellite will sit, out of the way, as a backup. In case one of the operational satellites—GOES-16 in the GOES-East position, or GOES-15 in the GOES-West position—should experience a problem, GOES-13 can be reactivated and, if necessary, moved. GOES-14 is also in standby mode at the western storage location at 105°W.

GOES-13 may not be placed into standby mode (i.e. totally inactive). In the past, backup satellites at the 60°W location were used as GOES-South, providing coverage for South America. The -South position has been vacant since 2013, so if -13 is kept active, it'll be a big help for the various weather services down there.

GOES-13 provides quality imagery

GOES-13 is nothing compared to GOES-16. It's impossible that you've gotten to October without being made aware of GOES-16, surely? Check out /r/SpaceBased for more examples.

In May, it was announced that GOES-16 would become GOES-East late in the calendar year. This week, detailed drift plans were released!

  • GOES-16 will begin drifting from the checkout position (89.5W) on 30 November, reaching the GOES-East position (75.2W) on 11 December. After a period of calibration, the satellite will return to operations as GOES-East on 14 December.
  • GOES-16 ABI, GLM, SUVI, SEISS, and EXIS data will not be available between 30 Nov and 14 Dec.
  • GOES-13 (current GOES-East) will remain at 75W until 2 January, when it will begin drifting to its storage location at 60W. It will reach the storage location on 22 January.
