Including Measurement Quality Objectives (MQOs) in MARSAME to support survey design and selection of measurement methods marks a major step forward from MARSSIM. The required measurement uncertainty is a critical MQO that is used to support a priori selection of measurement methods, validation of new measurement methods, and a posteriori assessment of measurement methods.

The calculation of the required measurement uncertainty presents a problem for many MARSAME users. This course defines required measurement uncertainty and discusses the role of MQOs in survey design using MARSAME, specifically related to selection of appropriate measurement methods.

Attendees will be provided with a copy of GUMCALC software for calculating uncertainty and will be instructed in the use of this software. Example problems will be provided and attendees will have an opportunity to select appropriate inputs for a specific situation and to calculate required measurement uncertainties using GUMCALC . The results of the example problems will be discussed and compared with field applications. Attendees will need to bring a computer to the course to participate in the exercises; they must have administrator privileges to install new software or have the GUMCALC software installed before arriving at the course.
