Stratospheric Analysis and Evaluation.
Evaluatim of the results of Project
Ashcan was made, together with a meteorological interpretation.
A report
was presented at the DBM conference in Minneapolis and a paper was submitted
to the AEC.
This paper was also transmitted to the UN Scientific Committee
and has been submitted for publication in the Journal of Geophysical Research.
Stratospheric data collected by the HASP program was evaluated.
To better understand the circulation of the stratosphere and stratospherictropospheric exchange processes, a study of ozone in the upper-atmosphere was
initiated with partial support from the AEC.
To utilize this natural atnmos-
pheric tracer, knowledge of the vertical and horizontal distribution of ozone
is needed.
A project to evaluate and compare three types of recently
developed ozonesondes was carried out at Lowry Air Force Base, Denver,
from April 13 to May 1.
balloon flights.
The evaluation tests consisted of 11 high-altitude
Each balloon carried a train of instruments to heights
averaging over 100,000 feet.
Preliminary work connected with the establishment of a new project on
stratospheric weather analysis, partially supported by AEC funds, has been
completed.
The project now occupies ample quarters well-furnished for the
job ahead.
Three trained analysts and five chartmen have been hired to
staff the project.
Drafting and printing of a map base suitable for the analysis and
subsequent reproduction of the 100-mb and 50-mb charts was the first task
completed.
For use in regions of sparse observations and at stations having
a short radiosonde flight, scattergrams were prepared for the month of July
to extrapolate data from the 100-mb to the 50-mb level.
Continental Chinese
data have been extracted from Japanese teletype and radio-intercept material
