The Global Environmental eMuLator (GEML) is a component of the experimental Global Deterministic Prediction System (GDPS) and is an artificial intelligence (AI)-based weather emulator trained on past atmospheric states. More specifically, this GEML model is based on data compatible with the ¼°, 13-level version of the GraphCast model (Lam et al. 2023) from DeepMind. It was trained and refined by ECCC, using ECMWF's ERA5 data (1979-2016) and operational analyses (2016-2021). The weights have been recalculated and are also available to the public. Forecasts are carried out twice daily, each with a 10-day lead time. It generates the reference large-scale temperature and horizontal wind fields, toward which GDPS's GEM forecasts are spectrally nudged. The geographical coverage is global with a horizontal resolution of 28 km. Data is available on 13 pressure levels, and employs a uniform latitude-longitude grid with 0.25-degree grid resolution. Six atmospheric variables defined on the 13 pressure levels, along with 4 surface variables are available every 6 hours.

For the best experience, please follow the instructions available in the resources.**In replacement of the former Canadian Digital Elevation Model (CDEM) that is no longer supported, the Medium Resolution Digital Elevation Model (MRDEM) product is a multi-source product that integrates elevation data from the Copernicus DEM** acquired during the TanDEM-X Mission (AIRBUS, 2022), and the High Resolution Digital Elevation Model data derived from airborne lidar. This product provides a complete, 30 meters resolution, nationwide coverage for Canada. It includes a Digital Terrain Model (DTM), a Digital Surface Model (DSM) and other derived products. The spatial coverage extends into the USA, where needed, to provide coverage for cross-border watersheds in support of hydrological studies and applications. The MRDEM-30-DSM is partially based on the GLO-30 version of the Copernicus DEM** (hereafter named GLO-30). Since elevation values from the GLO-30 are referenced to the EGM2008 geoid model, they were transformed to the Canadian Height Reference System of 2013 (CGVD2013), using the CGG2013 geoid model. Where available, the MRDEM-30-DSM integrates surface data from the lidar-derived HRDEM mosaic, resampled from 1 m to 30 m. The process to generate the MRDEM-30-DTM is more complex. Where available, the HRDEM Mosaic derived from lidar was used since it already provides reliable terrain elevation values. The HRDEM Mosaic data used was resampled from 1m to 30m. Elsewhere, the processing workflow combines a forest removal model and a settlement removal model that is applied to the GLO-30 values in order to estimate the terrain elevation values. Both datasets are projected to Canada Atlas Lambert NAD83 (CSRS) (EPSG:3979).The MRDEM is referenced to the CGVD2013 which is the reference standard for orthometric heights across Canada.The product Medium Resolution Digital Elevation Model (MRDEM) is part of the CanElevation Series created in support to the National Elevation Data Strategy implemented by NRCan.** This product was in part produced using Copernicus WorldDEM-30 © DLR e.V. 2010-2014 and © Airbus Defence and Space GmbH 2014- 2018 provided under COPERNICUS by the European Union and ESA; all rights reserved.The organisations in charge of the Copernicus program by law or by delegation do not incur any liability for any use of the Copernicus WorldDEM-30.

The Canadian long term satellite data record (LTDR) derived from 1-km resolution Advanced Very High Resolution Radiometer (AVHRR) data was produced by the Canada Center for Remote Sensing (CCRS). Processing included: geolocation, calibration, and compositing using Earth Observation Data Manager (Latifovic et al. 2005), cloud screening (Khlopenkov and Trishchenko, 2006), BRDF correction (Latifovic et. al., 2003), atmosphere and other corrections as described in Cihlar et. al. (2004). For temporal analysis of vegetation cross-sensor correction of Latifovic et al. (2012) is advised. Data collected by the AVHRR instrument on board the National Oceanic and Atmospheric Administration (NOAA) 9,11,14,16,17,18 and 19 satellites were used to generate Canada-wide 1-km 10-day AVHRR composites. Data are available starting in 1985. It is important to note that there are three types of AVHRR sensors: (i) AVHRR-1 flown onboard TIROS-N, NOAA-6, NOAA-8, and NOAA-10; (ii) AVHRR-2 flown onboard NOAA-7, NOAA-9, NOAA-11, NOAA-12, and NOAA-14; and (iii) AVHRR-3 currently operational onboard NOAA-15, NOAA-16, NOAA-17, NOAA-18 and NOAA-19. The AVHRR-1 has four channels, AVHRR-2 has five channels and the AVHRR-3 has six channels, although only five channels of AVHRR-3 can be operational at any one time. As such, channels 3A (1.6 m) and 3B (3.7 m) work interchangeably. The processing procedure was designed to minimize artefacts in AVHRR composite images. There are thirty six 10-day image composites per year. The following three processing levels are provided: P1) top of atmosphere reflectance and brightness temperature, P2) reflectance at surface and surface temperature and P3) reflectance at surface normalized to a common viewing geometry (BRDF normalization). The processing level P1 and P2 are provided for all 36 composites while level P3 is provided for 21 composites from April – October.

The dataset contains the digital boundaries for significant discovery licences, production licences, drilled wells, major pipelines and the jurisdictional boundary of the area administered by the Canada-Nova Scotia Offshore Energy Regulator (CNSOER), as well as the inactive Georges Bank permits formerly administered by the Canada Oil and Gas Lands Administration (COGLA). All production facilities have been removed and active projects were fully abandoned and decommissioned by November 2020. As of January 2022 there are no active exploration licences.A significant discovery licence (SDL) may be issued for lands within a declared significant discovery area under the Accord Acts. The term of a significant discovery licence is indefinite and was designed to maintain an explorer's rights during the period between first discovery and eventual production. Significant discovery licence interest representatives in 2021 include BP Canada Energy Company, ExxonMobil Canada Ltd., ExxonMobil Canada Properties, Ovintiv Canada ULC, and Shell Canada Limited. Most of the SDLs predate the CNSOEB; they were issued at various times from 1980 to 1986 by COGLA before the Offshore Board existed. On January 5, 1990, they were all rolled into CNSOEB’s governance. The only exception is SDL 2702 which was issued June 6, 2007.A production licence (PL) gives interest holders the right to produce petroleum in an area which is subject to a declared commercial discovery. In order to be declared a commercial discovery, an operator must demonstrate that the discovery contains reserves that will justify the investment of capital and effort to bring the discovery to production. A production licence has a term of 25 years but may be extended if commercial production is continuing or is likely to recommence.Production licence interest representatives in 2021 include ExxonMobil Canada Ltd. and Ovintiv Canada ULC. The PLs were effective on the following dates:• 2901, 2902: 1991-04-01• 2903, 2904, 2905, 2906: 1999-07-06• 2907: 2003-10-31• 2908: 2004-11-25• 2909, 2910, 2911: 2010-12-31 Inactive Georges Bank permit interest representatives include BP Canada Energy Company and Chevron Canada Ltd.Each production licence, significant discovery licence and inactive Georges Bank permit polygon is a mapped representation of the permit interest abstract. The offshore area is divided into grid areas and permit interest abstracts are defined by this land division. The land division system consists of grid areas, sections, and units – all referenced to the North American Datum of 1927 (NAD27). For more information on the Canada lands defined areas (Land Division), See: Canada oil and gas regulations land division (https://laws-lois.justice.gc.ca/eng/regulations/C.R.C.%2C_c._1518/page-1.html#h-525569 or https://www.cnsopb.ns.ca/resource-library/land-division-guideline).The area of a PL or SDL can be found in the permit interest abstract for that licence, available for download on the CNSOER's website (https://www.cnsopb.ns.ca/sites/default/files/resource/interest_summary_table.pdf) . The directory of wells point dataset contains the surface locations for all wells drilled in Offshore Nova Scotia. The file includes well names, locations, spud dates, termination dates, rig table elevations, water depths, well total depth, well type (exploratory, delineation, production, or injector), well result, and current status. Original data for wells drilled prior to 1990 was collected and maintained by the Geological Survey of Canada and COGLA. Data are also available on the Basin database online (https://basin.gdr.nrcan.gc.ca/index_e.php). CNSOER’s directory of wells was last updated January, 2020.Jurisdictional boundary point and lines datasets define the outer limit of the jurisdiction of the CNSOER, as described in the Canada-Nova Scotia Offshore Petroleum Resources Accord Implementation Act - Schedule 1 (Canada-Nova Scotia Offshore Petroleum Resources Accord Implementation Act (https://laws-lois.justice.gc.ca/eng/acts/C-7.8/page-1.html)), excluding the 200-nautical mile exclusive economic zone (EEZ) limit as described under Part VI of the United Nations Convention on the Law of the Sea (https://www.un.org/Depts/los/convention_agreements/texts/unclos/unclos_e.pdf?msclkid=5309c2b9cfc911ecb5bb107f67772ec1). The offshore gas pipeline polyline dataset contains locations of major pipelines in the CNSOER's jurisdictional area, associated with petroleum production in offshore Nova Scotia. This file is considered to be approximate and is not an official record. Some pipeline coordinates are sourced from CAD documents (DXF), supplied by operators. Some were created using ArcMap, digitized from paper records. As of October 2021, all pipelines within this file have been fully flushed with sea water and abandoned.All shapefiles were transformed into the NAD83 datum using the NTv2 transformation.
