How far north a particular _can_ include, it is approximately 65:45N at 72W (the current GOES-12 sub-satellite longitude). The Unidata-Wisconsin sectors, of course, will include points further north at locations east and west of the sub satellite longitude. Exactly how far north a particular sector _will_ include will depend on the actual scan from GOES-12, but it will never include points further north than approx. 65:45N at 72W. Since the actual satellite coverage varies with the scanning schedule set by NOAA, there is no way that we can tell you apriori how far north a particular sector will cover. >And we are currently extracting up to 60N. I just would like to know >how further North can I go? This depends on what your goal is: - if your goal is to go as far north as the most northerly points possible in the sectors, then you should go up to 70N - if your goal is to go as far as the most northerly points at the sub-satellite longitude, you can go up to 65:45N - if your goal is to never have any blank lines, you would need to go only as far north as the sector that has the lowest northerly coverage. I would never recommend this option since NOAA can change the scan coverage at any time. >Thanks in advance for a prompt and direct answer No worries.
