The NCAR/RAP IIDA utilizes not only numerical model data, but also surface observations, radar observations and information derived from the GOES-8 instrumentation on cloud location, cloud top temperatures and cloud top heights. Our development of an Alaskan version of the IIDA has had to take into account not only a relative lack of useful radar information but a relative wealth of satellite information available through both GOES and POES instrumentation due to our high latitude area of interest.
In this paper we present the methodology behind and sample products of the Alaska IIDA we have developed at UAF, with a strong emphasis on satellite aspects. We will describe the procedures used in incorporating data from not only GOES but POES platforms, the latter of which requires a blending of data from the two sources along the appropriate POES swath at the time of interest. We will also briefly discuss other potential satellite data inputs into future versions of the IIDA.
