Ice Classification, Metop-C Advanced SCATterometer (ASCAT), Arctic, Daily

Summary

This is 4km Metop-C Advanced SCATterometer (ASCAT) ice classification for the Arctic from NOAA.
Ice Class variable includes 5 discrete numerical values (1 to 5) corresponding to: (1) Land, (2) Water, (3) Seasonal, (4) Mixed, and (5) Perennial.
Disclaimer: Microwave-based ASCAT sea ice classification may not be reliable during Northern summer months or melt periods (approximately May to September) because melting snow and ice have a distinct microwave radar return that may prevent accurate identification of ice type

Dataset Description

The ASCAT Ice Classification system takes Enhanced Resolution (4.5 km x 4.5 km) ASCAT Normalized Radar Cross Section (NRCS) and in a two-step process creates an Ice Classification mask with 3 classes (seasonal, perennial, mixed). Primary Input data Enhanced Resolution (4.5 km x 4.5 km) ASCAT Normalized Radar Cross Section (NRCS) created by the Scatterometer Image Reconstruction (SIR) algorithm. Developed by David Long at BYU. National Ice Center's 4 km Interactive Snow and Ice Mask (IMS). Warning: Microwave-based ASCAT sea ice classification may not be reliable during Northern summer months or melt periods (approximately May to September) because melting snow and ice have a distinct microwave radar return that may prevent accurate identification of ice type.
