Title
SPDSS Task 48.2 - Development of Calibration Targets and Criteria - Phase 4
Description
This Technical Memorandum was undertaken under Task 48.2 of Phase 4 of the SPDSS, to develop calibration criteria, including selection of field data (targets) to be used during the model calibration. This TM summarizes the methodology and data that are anticipated to be used in the model calibration process.
