Deriving the normalised ion-neutral collision frequency from EISCAT observations
Common programme observations by the EISCAT UHF radar revealed an extended interval, post geomagnetic local noon on 03 April 1992, during which the F-region ion velocity orthogonal to the geomagnetic ®eld was signi®cantly enhanced, to values exceeding 2 km s corresponding to a perpendicular electric ®eld of some 100 mV m. Observations from this interval are used to illustrate a method by which ...
متن کاملDeriving Logic Programs from Observations
This chapter describes a method for deriving logic programs from observations that can be made of the progress of a computation. Such observations can be regarded as extrinsic speciications, and can be represented as directed acyclic graphs. Each computation that the system can perform is represented by a path through the graph which in turn can be described in rst order logic. Logic programs c...
متن کاملDeriving convective structure from microwave sounder observations
Microwave sounders have been used for many years to measure the thermodynamic state of the atmosphere, i.e. the three-dimensional distribution of temperature, water vapor and liquid water, both from space, from aircraft and from the ground. Currently, the most advanced satellite based microwave sounding system is the Advanced Microwave Sounding Unit (AMSU-A and-B) operating on a number of weath...
متن کاملDeriving Monotonic Function Envelopes from Observations*
Much work in qualitative physics involves constructing models of physical systems using functional descriptions such as "flow monotonically increases with pressure." Semiquantitative methods improve model precision by adding numerical envelopes to these monotonic functions . Ad hoc methods are normally used to determine these envelopes. This paper describes a systematic method for computing a b...
متن کاملDensity of neutral interstellar hydrogen at the termination shock from Ulysses pickup ion observations
Aims. By reevaluating a 13-month stretch of Ulysses SWICS H pickup ion measurements near 5 AU close to the ecliptic right after the previous solar minimum, this paper presents a determination of the neutral interstellar H density at the solar wind termination shock and implications for the density and ionization degree of hydrogen in the LIC. Methods. The density of neutral interstellar hydroge...
