Alaska Ocean Observing SystemDMAG Capabilities

Data management and modeling


Overview l.jpg
Overview

  • Data management

  • Modeling

  • Transfer

  • Access

  • Analysis

  • Visualization


Data management l.jpg
Data Management

Automation of…

  • Data transport (IN)

  • Storage and processing of new data

  • Product production

  • Data access; Data transport (OUT)

  • Data archive and safety

  • Metadata and data lineage


Modeling l.jpg
Modeling

  • Investigating ROMS modeling with biology & ice

  • Very experimental WRF-ARW runs in PWS, GOA, and SE Alaska

    • Infrastructure in place to allow automated runs of other models

    • Collaboration with AEFF

  • ARSC : near-operational WRF model run at 7.5 km statewide domain

  • Next challenges :

    • QA/QC of information for use as input to models

    • Data assimilation


Domains l.jpg
Domains

  • ROMS (NEP/SEBS)

  • WRF-ARW @ AOOS/AEFF (PWS, GOA, SE)

  • WRF-ARW @ ARSC (NorthAlaska6)

PWS 4km

AEFF RAMS GRID #3

NorthAlaska6 7.5 km

SEBS: Southeast

Bering Sea

SE 10 km

GOA 10km


Data transport in l.jpg
Data transport (IN)

Active data transport

  • FTP : 137.229.40.79

  • A specific username/password may be assigned

  • Strictly anonymous is also allowed

  • Scripting required to begin processing

  • RAMS/AEFF, webcams, monthly SWAN, cruise data


Data transport in7 l.jpg
Data transport (IN)

Passive data transport

  • AOOS grabs data

    • Straight up HTTP : OPeNDAP, screen scrape (NDBC)

    • Some other web service : SnoTel/AMBCS

    • FTP; OPeNDAP; …

  • Requires polling of remote server(s)

  • New data is detectable and leads to automatic processing


Access data transport out l.jpg
Access; Data transport (OUT)

  • Access to raw data for download and custom visualization (HTTP)

  • OPeNDAP services

  • Development of OGC GIS data protocols

    • Graphical front end : UMN Mapserver

    • WMS, WFS, and WCS layers : ArcIMS

  • Data Catalog Explorer (Query -> ASCII)

  • Metadata -> data ; Data -> metadata

  • Text, NetCDF, HDF and GIS shape file products can be created to user specifications

    • Maintain compatibility with IOOS protocols data transport, if possible


Access data transport out9 l.jpg
Access; Data transport (OUT)

  • Raw (HTTP) : http://ak.aoos.org/data/

  • OPeNDAP : http://ak.aoos.org/dap/data/

  • Data Catalog Explorer :

    • http://ak.aoos.org/op/data.php

  • UMN Mapserver (GIS) : beta

    • http://ak.aoos.org/xml/maps_i.php

  • Metadata :

    • http://ak.aoos.org/rest/metadata


Analysis l.jpg
Analysis

Open source software

  • Specialized graphics will require porting from commercial applications to open source software

  • Computations that require special tools, IDL or Matlab, will increase licensing, support and general processing overhead

  • AOOS provides basic analysis

  • More complex analysis is driven by user requests and support (it must be automated)




Visualization l.jpg
Visualization

  • Data Catalog Explorer

  • GIS web application : UMN Mapserver

  • Metadata -> Data

  • Custom visualization products

  • Custom analysis products

Homework action items needs l.jpg
Homework, action items, needs…

  • Get data and products to AOOS

    • Data: great, Graphics: ok; FTP, HTTP, OPeNDAP, IOOS protocol

  • Visualization needs

    • Send us examples of data and graphics

    • Snippets of code are also helpful

  • Data format and access needs

    • Special formats and/or structure need to be known in advance

    • Attempt to make it IOOS compatible

    • Data and products may be restricted

      • Automated, if static IP addressing is used

      • More difficult, if user authentication is required

  • Data and products can be delivered

    • If the process can be completely automated
