AirFuse provides several data fusion techniques designed to work with AirNow, PurpleAir, NOAA's Air Quality Forecast and NASA's Composition Forecast.

Overview

The standard driver applies Nearest Neighbor Averaging, Voronoi Neighbor Averaging (VNA), extended VNA (eVNA), and additive VNA (aVNA). eVNA corrects the model surface multiplying the ratio of obs:mod. aVNA is like eVNA, except it corrects teh model surface by subtracting the bias. For both eVNA and aVNA, the ratio or bias is interpolated from Voronoi neighbors using inverse distance weights.

AirFuse Examples

from airfuse.drivers import fuse

date = '2023-08-24T18Z'
pmpaths = fuse(
    obssource='airnow', species='pm25', startdate=date, model='naqfc'
)
o3paths = fuse(
    obssource='airnow', species='o3', startdate=date, model='naqfc'
)

Install

Using pip

airfuse currently requires the nna_methods package, which is another github repository. So, installing requires two calls to pip.

pip install git+https://github.com/barronh/nna_methods.git
pip install git+https://github.com/barronh/airfuse.git

From Downloaded Source

airfuse can also be installed by downloading the source code.

wget https://github.com/barronh/airfuse/archive/refs/heads/main.zip
unzip main
cd airfuse-main
pip install -r requirements.txt
pip install .
