# EarthLive: a dynamic wallpaper powered by Rainmeter
EarthLive is a [Rainmeter](https://www.rainmeter.net/) skin that fetches the latest daily natural color imagery of Earth from the [EPIC camera onboard the DSCOVR spacecraft](https://epic.gsfc.nasa.gov/) and displays it as the system wallpaper.

This project was inspired by the unofficial Twitter bot ([@dscovr_epic](https://twitter.com/dscovr_epic?lang=en)) created by [russss](https://github.com/russss/dscovr-epic).

## How it works
The skin uses Rainmeter's [WebParser plugin](https://docs.rainmeter.net/manual/plugins/webparser/) to fetch data provided by the [DSCOVR: EPIC API](https://epic.gsfc.nasa.gov/about/api) developed by NASA.
Image name, date, lat/long of the centroid, and more information is accessible as text from simply visiting a URL.
The image file is located at a systematic location with only the name changing for each picture.

Once data is fetched from NASA, the image is displayed and the date it was taken is overlaid on top.

The skin updates once per second. NASA's server is pinged once every 10 minutes.

## Installation
* Run the included `.rmskin` package to automatically install the skin.
* Place `EarthLive.ini` and `Settings.ini` in a directory within `C:\User\your-username\Documents\Rainmeter\Skins` and load the `EarthLive.ini` skin from the Rainmeter Manage window.

## Settings
Settings may be changed by commenting/uncommenting chunks of code in `Settings.ini`.
Currently the only available setting is whether to fetch "natural" color or "enhanced" color images.

## Plans for future versions
* Aesthetically pleasing photoprocessing, such as the processing done by the [@dscovr_epic](https://twitter.com/dscovr_epic?lang=en)
* Geolocation from the lat/long coordinates of the image's centroid that are included in image metadata
* "Slide show" mode that fetches multiple recent images and forms an animated wallpaper

## About DSCOVR: EPIC
__[Earth Polychromatic Imaging Camera (EPIC)](https://epic.gsfc.nasa.gov/epic)__:
> EPIC (Earth Polychromatic Imaging Camera) is a 10-channel spectroradiometer (317 – 780 nm) onboard NOAA’s DSCOVR (Deep Space Climate Observatory) spacecraft. EPIC provides 10 narrow band spectral images of the entire sunlit face of Earth using a 2048x2048 pixel CCD (Charge Coupled Device) detector coupled to a 30-cm aperture Cassegrain telescope (Figure 1).

>
> The DSCOVR spacecraft is located at the Earth-Sun Lagrange-1 (L-1) point giving EPIC a unique angular perspective that will be used in science applications to measure ozone, aerosols, cloud reflectivity, cloud height, vegetation properties, and UV radiation estimates at Earth's surface.

__[EPIC's API](https://epic.gsfc.nasa.gov/about/api)__:
> The EPIC API provides information on the daily imagery collected by DSCOVR's Earth Polychromatic Imaging Camera (EPIC) instrument. Uniquely positioned at the Earth-Sun Lagrange point, EPIC provides full disc imagery of the Earth and captures unique perspectives of certain astronomical events such as lunar transits using a 2048x2048 pixel CCD (Charge Coupled Device) detector coupled to a 30-cm aperture Cassegrain telescope.

All DSCOVR EPIC data products are archived and publicly distributed through the NASA Langley Atmospheric Science Data Center (ASDC): https://eosweb.larc.nasa.gov.
