# Weather Models

The V360 platform operates utilizing tailored forecast models in both the user interface and API. These models are designed to support low-altitude aviation decision-making by delivering forecast guidance tailored to the operational needs of advanced air mobility and sUAS users. Available model guidance may vary by market, sensor availability, and subscription level.

### TruWeather Blend

The TruWeather Blend is the primary forecast guidance used across the V360 platform and drives all of the Decision Products. Rather than relying on a single model source, it combines multiple model input selected by our team of expert meteorologists to maximize the benefits and reduce the limitations of available models. A unified forecast designed to provide more consistent and operationally useful guidance for weather-sensitive aviation activities.

### SNAAP

SNAAP (System for Neighborhood-Scale Atmospheric Analysis & Prediction) is TruWeather’s proprietary subregional forecast model developed to improve short-range weather guidance, or Nowcast, for advanced air mobility and sUAS operations. It incorporates traditional weather observations along with data from novel sensors integrated into the V360 network, providing enhanced spatial detail and improved awareness of low-altitude conditions

### SWAPS

SWAPS (Street-Scale Wind Analysis & Prediction System) is TruWeather’s highest-resolution proprietary model, designed to provide extremely high-resolution and 3D guidance within smaller, focused domains. By combining very high spatial resolution with computational fluid dynamics, SWAPS helps represent how wind flows around buildings, trees, and other obstacles, offering bespoke insights for operations in complex urban or obstructed environments

SWAPS demonstrations for the Elizabethtown, TX window are available through the V360 user interface. To access the demonstration video:

{% stepper %}
{% step %}
Set a location in the user interface near Fort Worth, TX.
{% endstep %}

{% step %}
Click <mark style="color:blue;">**SWAPS 3D Wind**</mark> from the left side menu.
{% endstep %}

{% step %}
A new webpage will open with an animation of the latest run for the SWAPS window.
{% endstep %}
{% endstepper %}

This demonstration video depicts a comparison of TruWeather’s SWAPS against NOAA’s High Resolution Rapid Refresh (HRRR) model, which is considered the standard utilized amongst the AAM and sUAS market for weather prediction. Throughout the video, the model depicted by the moving particles will switch back and forth between SWAPS and HRRR. Additionally, color shaded regions will depict areas in which SWAPS and HRRR differ on wind speed and direction.

{% hint style="info" %}
Video depicts latest model runs, therefore videos will not always show the same data.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://truweathersolutions.gitbook.io/info/documentation/weather-models.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
