Again, I have not kept up on what satellite instruments are now flying.

Total ozone values are shown for high southern latitudes as measured by a satellite instrument.

Global total ozone values decreased by an average of a few percent in the last two decades, as measured by satellite instruments.

The satellite instruments will gather data on Solar storms in the upper atmosphere.

Since satellite instruments cannot measure the constituent directly, we need to perform some sort of inversion.

Lyman-alpha astronomy must therefore ordinarily be carried out by satellite borne instruments.

Since 1978, a series of satellite instruments have measured the energy output of the sun directly.

The best available data, however, taken with globe-circling satellite instruments since 1979, show no increase at all.

But the satellite instruments offer one serious disadvantage: their remoteness.

Although the ground instruments do not give comprehensive global data, they provide a check on the accuracy of the satellite instruments.
