Prach nad Texasom

Novinka

Satelit GOES-16 začína vedcom poskytovať prvé údaje vo vysokom rozlíšení. Takto vyzerá prach, ktorý sa vplyvom silného vetra zdvihol nad oblasť amerického Texasu.

Dust clouds sweep across north-central Texas in this 1-km GOES-16 composite-color animation from 2030 to 2310 UTC on February 23, 2017.

As this animation suggests, the ability of GOES-16's Advanced Baseline Imager (ABI) to provide such high-resolution imagery in color will be a boon to meteorologists as it will make it easier for them to identify different atmospheric or meteorological phenomena, such as dust from other types of clouds. As shown here, the brown-colored dust is easy to differentiate from smaller, white clouds mixed in with it.

Composite-color images from GOES-16 are created by combining data from three of ABI's 16-bands -- band 1 (blue visible), band 2 (red visible) and band 3 (near-infrared vegetation) -- to produce a range of colors within visible part of the electromagnetic spectrum (think the colors of the rainbow, ROYGBIV).

Note: GOES-16 data are currently experimental and under-going testing and hence should not be used operationally.
