Preparing Data for use in HOPS

The examination and preparation of data for use in HOPS is an important undertaking. During our real-time forecasting operations, nearly half of our resources will be devoted to it. Data should never be put into a dynamical model without an examination for consistency and reliability.

The recommended data format for HOPS is an ASCII format called MODS. This format is described in Readme.datamng. The primary advantage of an ASCII format (besides portability) is the ease it provides the user for "hands on" editing.


This package is a series of programs to manage data for HOPS. Currently this package is geared towards in situ profile data. The main purpose of this package is to formalize the most frequent operations performed on the data. Functionally, this package can be described as:

Inquiry codes
File manipulation codes
Data manipulation codes
Data conversion codes


This program is designed to add salinity to temperature-depth profiles. The purpose of the program is to eliminate a particular type of inconsistency. Say a CTD survey (depth, temperature, salinity) is augments with XBTs (depth, temperature). The end result can be a resolution mis-match between the temperature and salinity data. The worst case scenario would be the creation of fictitious density fronts from the mis-match. The goal is to create consistent salinities based on the local water mass properties.

This program should be used with caution. A poorly designed, inconsistent salinity is worse than none at all.
