Introduction
NGDC maintains a variety of Ionosonde data holdings. If you're interested in invidividual observations, please use the hourly summary buttons to the left and the documentation for the query interface below.If you're interested in other Ionosonde inventory interfaces (e.g. film, etc.), please use the buttons to the left under the category of 'Additional Inventories'
The Master Ionosonde Data Set (MIDS) Ionosonde Inventory, is an inventory of all individual ionosonde
soundings managed by the National Geophysical Data Center (NGDC). This interface offers both an interactive
form based, and REST based access points to the inventory. Using the highly flexible forms triggered by the
buttons to the left, you will be able to construct a query against this catalog tailored to your specific needs.
The query that results provides you a complete URL which can be shared with colleagues and whose parameters
can be adjusted at any time. Presently, the inventory supports a colored summary of ionosonde records along
with links to the corresponding data available online.
Contact Rob Redmon for scientific questions and data requests,
or Peter Elespuru for questions about the website or query interface.
Query Interface Summary
The query interface has 6 parameters:
- report
- station
- extension
- contentType
- dateFrom
- dateTo
The report parameter currently supports 3 values, of which 1 is active (hourly). 'hourly', 'daily' ,'monthly'
The full set of allowed values for the station, extension and contentType parameters are shown in the forms accessed by the buttons on the left.
The dateFrom and dateTo parameters accept and can parse a date in many different formats. If you specify something invalid
you'll be notified, but some examples are 'YYYY-MM-DD HH:MM:SS' and 'Sun%20Aug%2008%202010%2000:00:00%20GMT-0600%20(MDT)'
spaces and other special characters will be accepted whether or not you URI encode them, such as space = %20 as an encoded value.
For example, to generate a table of inventory holdings for the BC840 station, SAO extension,
of scaled content type, you would form a query like the following and provide this after the initial http://...
after 'inventory', as http://.../inventory/iono?... which becomes
http://spidr.ngdc.noaa.gov:80/inventory/iono?report=hourly&station=BC840&extension=SAO&contentType=scaled&dateFrom=Sun%20Aug%2001%202010%2000:00:00%20GMT-0600%20(MDT)&dateTo=Sun%20Aug%2008%202010%2000:00:00%20GMT-0600%20(MDT)
