PASS-SWIO Training

In this section we provide access to the training material developed and provided for the PASS-SWIO Project.

PASS-SWIO Training - Portagauge installation and operation

Training for installation and operation of the Portagauge was provided to DGM staff during the installation of the Portagauge in Toamasina Harbour on 12-16 June 2023. The installation and operation manual is available in English and French

PASS-SWIO Training - Tide Gauge and Satellite Altimeter Data Processing and Validation

The training in Tide Gauge and Satellite Altimeter Sea Level Data Processing and Validation was delivered through an online workshop in October 2023, and in a face to face meeting at the DGM offices in Antanarivo in February 2024. Below we give an outline of the training provided and provide links to the training material.

Training Objectives
To ensure Portagauge end users (DGM) are fully trained in the processing of satellite altimeter and tide gauge data, and in cross-validating these data against each other.

Contents

Checking and Validation of Tide Gauge sea level data.
- This covers the pre-processing and checking of data of raw tide gauge data as received from the PASS-SWIO Portagauge, and then the validation and analysis to generate tidal constituents and other key parameters.
- For this you will need the TASK tidal analysis software, available from the National Oceanography Centre on request
Processing and Submission of Portagauge GNSS position data.

This covers the pre-processing and checking of the GNSS data as received from the PASS-SWIO Portagauge, to provide precise location information.

Satellite altimeter data: Accessing and preprocessing.
- This covers accessing the Level 3 along-track satellite altimeter data from CMEMS and processing them into a format for processing with python code developed for the PASS-SWIO project.
- For this you will need the python code written for the project (see below)
Satellite altimeter data: Validation and analysis of sea level variability.

This covers using python code to cross-validate the satellite altimeter and tide gauge sea level data, and to generate plots to support analysis of sea level variability.
For this you will need the python code written for the project (see below)

Preparation
We list some other resources below, which are needed for data processing
