Public access to the SalishSeaCast model products
Brought to you by SalishSeaCast UBC EOAS MEOPAR NOAA
ERDDAP is a data server that gives you a simple, consistent way to download subsets of scientific datasets in common file formats and make graphs and maps.
This particular ERDDAP installation has model product datasets from the SalishSeaCast system run by the Mesoscale Ocean and Atmospheric Dynamics (MOAD) group in the Department of Earth, Ocean, and Atmospheric Sciences (EOAS) at the University of British Columbia (UBC). Available datasets include surface and 3D fields of currents, temperature, salinity, sea surface height, biological and chemical tracers from NEMO and FVCOM, and wave fields WaveWatch3(TM), as well as the Environment and Climate Change Canada (ECCC) High Resolution Deterministic Preduction System (HRDPS) atmospheric model fields used to force the models. Also available are aggregated datasets from selected Ocean Networks Canada (ONC) real-time sensors, and a real-time current dataset from a Vancouver Fraser Port Authority (VFPA) sensor at the 2nd Narrows railway bridge in Vancouver Harbour.

NEMO Model Updated on 21-Jun-2019
A new, improved version of the SalishSeaCast NEMO model has been running since late-2018.
A hindcast using that model configuration has been completed from 2015-01-01 to present.
The NEMO datasets here now come from from that model configuration.
They are identified with a

The version part of the rolling forecast dataset ids was dropped on 2-Jul-2019 to reflect the fact that those datasets transition smoothly from one model version to the next. Please see the summary metadata item to what model version is producing the most recent fields in the rolling forecast datasets.
Citing SalishSeaCast Datasets
If you use datasets from this ERDDAP server in your research, please reference it with wording similar to these examples, and include citations of the publications below.
Example reference for physics-only datasets:
Velocity, temperature, and salinity fields from the SalishSeaCast model (Soontiens et al, 2016; Soontiens and Allen, 2017) were downloaded from their ERDDAP server (https://salishsea.eos.ubc.ca/erddap/) on
Example reference for biological datasets:
Nitrate, silicon, and diatom fields from the SalishSeaCast model (Soontiens et al, 2016; Moore-Maley et al, 2016; Soontiens and Allen, 2017) were downloaded from their ERDDAP server (https://salishsea.eos.ubc.ca/erddap/) on

Easier Access to Scientific DataOur focus is on making it easier for you to get scientific data.
Different scientific communities have developed different types of data servers.
For example, OPeNDAP, WCS, SOS, OBIS, and countless custom web pages with forms. Each is great on its own. But without ERDDAP, it is difficult to get data from different types of servers:
ERDDAP unifies the different types of data servers so you have a consistent way to get the data you want, in the format you want.
For a quick introduction to ERDDAP, watch the first half of this video. (5 minutes) In it, a scientist downloads ocean currents forecast data from ERDDAP to model a toxic spill in the ocean using NOAA's GNOME software (in 5 minutes!). Thanks to Rich Signell. (One tiny error in the video: when searching for datasets, don't use AND between search terms. It is implicit.)
Data Providers: You can set up your own ERDDAP server and serve your own data. ERDDAP is free and open source. It uses Apache-like licenses, so you can do anything you want with it. ERDDAP's appearance is customizable, so your ERDDAP will reflect your institution, not NOAA. The small effort to set up ERDDAP brings many benefits. If you already have a web service for distributing your data, you can set up ERDDAP to access your data via the existing service or via the source files or database. Then, people will have another way to access your data and will be able to download the data in additional file formats or as graphs or maps. ERDDAP has been installed by over 60 organizations worldwide. NOAA's Data Access Procedural Directive includes ERDDAP in its list of recommended data servers for use by groups within NOAA.
Start Using ERDDAP:
|Griddap lets you use the OPeNDAP hyperslab protocol to request data subsets, graphs, and maps from gridded datasets (for example, satellite data and climate model data). griddap documentation|
|Tabledap lets you use the OPeNDAP constraint/selection protocol to request data subsets, graphs, and maps from tabular datasets (for example, buoy data). tabledap documentation|
|ERDDAP's "files" system lets you browse a virtual file system and download source data files. WARNING! The dataset's metadata and variable names in these source files may be different than elsewhere in ERDDAP! You might prefer using the dataset's Data Access Form instead. "files" documentation|
|The Web Map Service (WMS) lets you request an image with data plotted on a map. WMS documentation|
In addition to serving data, ERDDAP has some handy converters:
