Agroclimatology
Ruby client for interacting with the NASA (POWER) Agroclimatology Web Resource
Initial functionality is focused on getting solar radiation data for a given latitude and longitude. Other solar radiation and meteorological query parameters will be available in subsequent versions.
Installation
Add this line to your application's Gemfile:
gem 'agroclimatology'And then execute:
$ bundle
Or install it yourself as:
$ gem install agroclimatology
Usage
Required params
- latitude
- longitude
Optional params
- year_start (default: 1983)
- year_end (default: current year)
Agroclimatology.fetch(latitude, longitude, year_start, year_end)Examples
Fetch all solar radiation data
Agroclimatology.fetch(37.752798, -100.017079)Fetch solar radiation data from 2015 - 2016
Agroclimatology.fetch(-26.660446, 152.964647, 2015, 2016)[
{
:year => "2015",
:day_of_year => "1",
:rad_atmosphere => "42.84",
:rad_surface => "27.47",
:rad_flux => "34.78"
},
{
:year => "2015",
:day_of_year => "2",
:rad_atmosphere => "43.27",
:rad_surface => "23.00",
:rad_flux => "34.81"
},
]Output
Ruby object containing array of hashes for every day included in year_start - year_end range
- year - Year
- day_of_year - Day of Year
- rad_atmosphere - Average Top-of-atmosphere Insolation (MJ/m^2/day)
- rad_surface - Average Insolation Incident On A Horizontal Surface (MJ/m^2/day)
- rad_flux - Average Downward Longwave Radiative Flux (MJ/m^2/day)
Development
After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment. To install this gem onto your local machine, run bundle exec rake install.
