General Questions & FAQs
The answer is yes! There are several ways to programmatically access NSIDC data products and metadata using Application Programming Interfaces (APIs). We also provide the ability to access data using an FTP client.
First, the spatial resolution of AMSR/ADEOS-II and AMSR-E/Aqua data doubles the resolution of Scanning Multichannel Microwave Radiometer (SMMR) and Special Sensor Microwave/Imager (SSM/I) data.
On 25 October 2003, at 8:49 a.m. (JST), JAXA discovered that ADEOS-II had been switched to light load mode due to an unknown anomaly. (Light load is a mode in which all observation equipment is automatically turned off to minimize power consumption).
How to Articles
Some data sets specify dates using the year and day of year rather than the year, month, and day of month. The day of year (DOY) is the sequential day number starting with day 1 on January 1st.
Many NSIDC DAAC data sets can be accessed using the NSIDC DAAC's Data Access Tool. This tool provides the ability to search and filter data with spatial and temporal constraints using a map-based interface.Users have the option to
To convert HDF5 files into binary format you will need to use the h5dump utility, which is part of the HDF5 distribution available from the HDF Group. How you install HDF5 depends on your operating system.
