Water production increases by weather modification are subject to many factors. First, meteorologist and pilots must perform at high levels, but natural factors such as cloud targets are needed. During 2011, the driest one-year period on record in Texas, cloud targets were few and far between, limiting the production for the season. However, during wet years like 2007 and 2009, plenty more opportunities are present for cloud seeding. These are the years the programs can take advantage of in preparation for years like 2011.

Acre-Feet Increases per TITAN Evaluation

Radar data is observed using TITAN, a software program engineered by scientists at NCAR. This software is able to isolate clouds and provide parameters of the cloud. These parameters can be tracked during the operation providing important details of the changes the cloud experiences once seeded. Also, this data is sent off and independently evaluated where seeded clouds are compared to a number of control clouds. Evaluations in Texas have been ongoing since 2001, and for the WTWMA program, a 15% increase of precipitation has been found. Continue a program for a decade, and bank 1.5 years worth of precipitation.
