Space has a hostile radiation environment that increases the risk of cancers in humans and malfunctions in spacecraft electronics. The types of space radiation of primary concern are:
Galactic Cosmic Rays from outside our solar system generated by
supernovae and other phenomena;
Solar Energetic Particles produced by the Sun during intense and
sporadic bursts of activity; and
Trapped Radiation: energetic particles confined by Earth's magnetic
field, usually comprising an inner belt of mostly high energy protons
and an outer belt dominated by lower energy electrons and plasma.
Understanding the space radiation environment for a particular mission profile is becoming increasingly important. Commercial off-the-shelf electronic components that aren't resilient to space radiation are now prevalent. Longer duration missions to cislunar space, Mars, and beyond are placing astronauts at greater risk of radiation exposure.

Welcome to the Daymet Single Pixel Extraction Tool API. You can use this API to download daily surface data within the Daymet database in a csv or json format for a single point. This API allows users to query a single geographic point by latitude and longitude in decimal degrees. A routine is executed that translates the (lon, lat) coordinates into projected Daymet (x,y) Lambert Conformal Coordinates. These coordinates are used to access the Daymet database of daily interpolated surface weather variables. Daily data from the nearest 1 km x 1 km Daymet grid cell are extracted from the database.

Since 2006, Gisgraphy is a free, open source framework that offers the possibility to do geolocalisation and geocoding via Java APIs or REST webservices. Because geocoding is nothing without data, it provides an easy to use importer that will automatically download and import the necessary (free) data to your local database (OpenStreetMap, Geonames and Quattroshapes: more than 100 million entries). You can also add your own data with the Web interface or the importer connectors provided. Gisgraphy is production ready, and has been designed to be scalable(load balanced), performant and used in other languages than just java : results can be output in XML, JSON, PHP, Python, Ruby, YAML, GeoRSS, and Atom. One of the most popular GPS tracking System (OpenGTS) also includes a Gisgraphy client...Gisgraphy is a framework. As a result it's flexible and powerful enough to be used in a lot of different use cases. read more
if you use the premium servers, you can use the api key to test the webservices

Before using this API, we recommend you read our Authorization Guide for more information on how to generate an access token.
Please also be aware that our test environment is based on a subset of the production, if you are not returning any results try with big cities/airports like LON (London) or NYC (New-York).

Furkot provides Rest API to access user trip data.
Using Furkot API an application can list user trips and display stops for a specific trip.
Furkot API uses OAuth2 protocol to authorize applications to access data on behalf of users.

Our atmosphere protects us from a hostile space radiation environment comprising high energy particles of solar and intergalactic origin. Solar radiation is significant during unpredictable and short lived solar flares and coronal mass ejections (CMEs); however, galactic cosmic radiation (GCR) is omnipresent. The GCR intensity varies with latitude, longitude, and time due to effects of solar activity on the interplanetary magnetic field, as well as the Earth's magnetic field. Space radiation collides with gases in the atmosphere, leading to a complex shower of high energy radiation, the intensity and composition of which varies spatially and temporally. Excessive exposure to radiation can damage DNA and lead to long-term health effects such as an increased risk of cancer. Resulting radiation levels at commercial aircraft altitudes are greater than at sea level due. Aircrew are classified as radiation workers in some countries; however, planning to limit their exposure, and monitoring, is generally lacking. Both real-time measurements and predictive models of radiation in the atmosphere are important to mitigate the radiation risk crew.
We host a RESTful API to models of cosmic ray induced ionising radiation in the atmosphere. The PARMA or CARI7 endpoints can be used to calculate Effective Dose or Ambient Dose Equivalent at a point.
The Route Dose API calculates the same quantities along a great circle route between two airports using CARI7.
