MODIS/Aqua Sea Ice Extent Daily L3 Global 1km EASE-Grid Day V005

<p class="notice">A newer version of this data set (Version 6) is available.<br /> <a href="https://nsidc.org/data/myd29p1d/">Go to Version 6</a></p> MODIS/Aqua Sea Ice Extent Daily L3 Global 1km Equal Area Scalable Earth Grid (EASE-Grid) Day (MYD29P1D) data set contains fields for Sea Ice by Reflectance, Sea Ice by Reflectance Spatial QA, Ice Surface Temperature (IST), and Ice Surface Temperature Spatial QA in Hierarchical Data Format-Earth Observing System (HDF-EOS) format, along with corresponding metadata. The fields Sea Ice by IST and Combined Sea Ice that were in Version 4 (V004) were removed from Version 5 (V005). MYD29P1D V005, the latest version of the Moderate Resolution Imaging Spectroradiometer (MODIS) data, consists of 954 km x 954 km tiles of 1 km resolution data gridded in the Lambert Azimuth Equal Area map projection. The sea ice algorithm uses a Normalized Difference Snow Index (NDSI) modified for sea ice to distinguish sea ice from open ocean, based on reflective and thermal characteristics.

Description: Using this service, data from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) can be accessed directly from our HTTPS file system, or through our Application Programming Interface (API). This API offers you the ability to programmatically order and bulk-download data using temporal and spatial filters without the need to script against NSIDC's data directory structure. This may be valuable if you are interested in incorporating data access commands into your analysis or visualization code.
NSIDC_ECS_S4S View Service Record
Type: NOT PROVIDED
Description: Our subscription service automatically sends you new data as they are delivered from active NASA satellite missions. This service is convenient if you require the latest data for a specific region, but you do not want to actively search and order data files regularly. Advanced customization services including reformatting, reprojection, and subsetting are also available with your subscription.
