IV. OPERATIONAL SUMMARY - 1993

Table 1, on the following page, summarizes relevant 1993 WKWM
Program operational flight and seeding information plus all days
upon which crop-hail insurance claims were reported. Each flight
day was broken down into whether the flying for the day was:

R...to increase Rain only

H...to reduce Hail only

C...Qombined, to increase rain and reduce hail, both

O...Qbservation---cloud examination, no seeding performed

Other pertinent information relating to operations are to be
found in the back of this report in the following appendices:

(1) Appendix A - Historic Project Operational Activity Summary
(seeding and observation flights)

(2) Appendix B - Historic Monthly Number of seeding Days for
Hail and/or Rain Augmentation

(3) Appendix C - Historic Numbers of Monthly Flight Hours,
Seeding Hours and Seeding Agent Dispensed

This was the second consecutive year with 5 aircraft assigned
to the WKWM Program. No new operational records were set this past
year in flight numbers or hours, seeding time or amounts of seeding
agents dispensed or radar run time. Table 1 shows the relevant
operational numbers accumulated in 1993 and the crop hail insurance
claim summary through Oct. 12th.

There were 358 total flights of which 229 were seeding and 63
were observations. Total cloud base and cloud-top seeding flight
time amounted to 625.4 hours. Actual seeding time at cloud base
was 257.3 hours (15,436 minutes) and the cloud top in-cloud seeding
time was 23.2 hours (83,560 seconds); 55,845 grams silver iodide
were burned and 3158.6 kg of dry ice were released, respectively.
Of the 229 seeding flights, 189 were at cloud base and 40 at cloud
top.
