KNN-WG

KNN-WG is a cool software that helps with weather prediction using a simple method called K-nearest neighbors (K-NN). Weather forecasting can be tricky because it needs a lot of data and smart people to figure out patterns. With KNN-WG, researchers can easily run models and simulate weather data in a friendly digital space.

Easy Interface for Everyone

The interface of KNN-WG is pretty straightforward. It has some tabs that make it easy to manage your data and use the K-NN technique without getting overwhelmed. You can pull information from Excel files, whether they're in XLS or XLSX format. Sadly, you can't use other formats as input right now, but hey, at least Excel is super common!

Working with Weather Variables

This software lets you work with many weather variables like maximum and minimum temperatures, rainfall amounts, humidity levels, solar radiation (Srad), evapotranspiration (ETo), and wind speed. You will need to pick the right column for each value manually when you're loading your data. It would be nice if you could tweak how the spreadsheet looks while importing it - that could save some time!

Running Your Predictions

Once your data is loaded up, you can set it up as input for the K-NN model in the next tab. To do this properly, just select your base period and future period since this method works on the idea that today's weather is kind of like yesterday's weather.

Understanding Output Data

KNN-WG shows you output data for all the variables you've chosen, so you get daily predictions right there on your screen! Plus, it creates an output plot which makes understanding the results way easier. The app even calculates efficiency criteria and lets you compare how K-NN stacks up against other models.
