WACR Fields for DOD

7/18/2005

General Comments/Questions

Let's convert heights to meters above MSL, like MMCR for consistency. Still need to add SGP altitude to Heights field.
rtds: This field consists of 6 temperatures of different system components. Shall we break it up or leave it as a two-dimensional array? I think it partly depends on how easy it is for Annette to describe the 6 different temperatures in one field.
Do we want to have one time_offset or separate ones for the co-pol and cross-pol moments? If we have just one time field, then when we are collecting co and cross measurements, every other value will be missing for each set of moments. Are there other examples of data sets with several different time fields?
