OMI very fast delivery
frequently asked questions
- What means VFD?
It means "Very Fast Delivery". VFD-products are
processed and published immediately after the
satellite overpasses the Satellite Data Center at
Sodankyla, Northern Finland. The data is received as
a Direct Broadcast (DB) which means that the
instrument measures the data and, in the same time, continuously sends it
down to Earth.
- What is a composite image?
In a composite image several individual
OMI VFD images are merged together. The new images overlap
the older ones, although some part of the older images
can also be seen. The composite images are provided
for the previous day and for the current day.
- Can I use these
Yes, but only for uncommercial purposes. If you
use the images, for example, in a presentation, we
kindly ask that you include an acknowledgement as
follows: "OMI VFD images are provided by FMI. OMI is
a joint effort of KNMI, NASA, and FMI."
