MILOS520 VOS AWS

Selwyn Alpert

Vaisala, Inc.

Woburn, MA


Overview
OVERVIEW

  • WMO Objective:

    • Increase observations over the oceans

    • Utilize buoys, floats, and ships

  • VOS - Voluntary Observing Ships

    • Synoptic data (real-time communication) for improved forecasting

  • VOSClim - Voluntary observing ship data for improved climatalogical data base (no need for real time)

  • MILOS520 VOS AWS - New Vaisala AWS configuration for VOS applications


Milos aws
MILOS AWS

  • AWS based on Milos Series of AWS -

  • over 2000 built from mid-70’s to

  • present (M200, M500, M520)

  • First Ship applications during 80’s

  • Total Installed base over 85 systems

  • HighData Quality

  • High quality sensors

  • Measurement validation

    • Min / Max check

    • Step limit check

  • Calculation validation

    • 80 % of data requirement

  • Validation for manual inputs


Milos520 vos aws8

  • Communication

  • Inmarsat C as default

  • Goes, GTS and Meteosat

  • Argos / SCD

  • Others


Inmarsat C Communication

  • Inmarsat C data reporting mode: Australia VOS

  • In co-operation with the Australian Met Bureau

    • The message reported is a binary subset of the full ship message.

    • The data is sent via Inmarsat C using the data reporting mode, which reduces the running costs. The data is sent to the Bureau via the Perth Land Earth Station.

    • The data is decoded within the Bureau and is then placed on the GTS as a full Ship message.
