- Operational ADT 8.2.1 was utilized for both estimates. GOES-East was used
for operational runs while GOES-R was used for Proving Ground "PG" runs.
- Statistics utiize the NHC Working Best Track information for intensity and
position information w/in +/- 3 hours of aircraft reconnaissance
- Statisitcs are homogeneous. ADT estimates must be w/in approximately 15 minutes
of each other and closest eastimates w/in 2 hours of Best Track.
- Intensity matches only utilize Best Track estimtes with HU (Hurricane), TS (Tropical
Storm), or TD (Tropical Depression) designations, while Position matches are not
constrained by storm type designation.
- ADT MSLP estimates have been derived using the CKZ methodology.
- Intensity histogram bins are centered upon the value specified.
The exact bin extents are (in knots):
