Nimbus Advanced Vidicon Camera System Remapped Visible Imagery Daily L3, HDF5, Version 1
Data set id:
NmAVCS3H
DOI: 10.5067/NIMBUS/NmAVCS3H
This is the most recent version of these data.

Overview

This data set (NmAVCS3H) consists of daily, global image composites constructed from Nimbus 1 (1964) and Nimbus 2 (1966) Advanced Vidicon Camera System (AVCS) imagery. Each composite is provided as a set of three HDF5-formatted files: separate North and South Polar projections in the 5 km Equal-Area Scalable Earth Grid (EASE-Grid) and an equatorial projection in a 10 km equidistant grid for the region between 60 N and 60 S.
