MCD Visualizer for QGIS

MCD Visualizer is a QGIS plugin designed to analyze and visualize atmospheric data from the Mars Climate Database (MCD).

⚠️ CRITICAL REQUIREMENTS

Due to license restrictions and file size, this plugin does NOT include the MCD data.

1. Data Requirements (Mandatory)

You must have a local copy of the full Mars Climate Database (v5 or v6). On the first run, the plugin will ask you to select your local data folder.

Your data folder MUST contain ALL the following subdirectories:

Climate Scenarios:

• clim_aveEUV (Yearly Average)
• cold
• warm
• strm (Dust Storm)

Martian Years (Historic Data):

• MY24
• MY25
• MY26
• MY27
• MY28
• MY29
• MY30
• MY31
• MY32
• MY33
• MY34
• MY35

Note: If you select a folder that is missing any of these subdirectories, the plugin may not function correctly.

2. Software Requirements

This plugin requires external Python libraries not included in standard QGIS installations:

• xarray
• netCDF4

How to install them: Open your OSGeo4W Shell (Windows) or Terminal (Mac/Linux) and run:

pip install xarray netCDF4

## Features
*   **Map Tool:** Visualize atmospheric variables (Temperature, Pressure, Wind, etc.) on a 2D map with spatial interpolation option.
*   **Profile Tool:** Generate vertical profiles, temporal evolution charts, and 2D cross-sections.
*   **Customization:** Toggle between "Raw Data" (exact grid points) and "Interpolated" modes for smoother visualization.
*   **MOLA Integration:** Automatically overlays MOLA topography isolines for context.

## Installation
1.  Open QGIS.
2.  Go to **Plugins > Manage and Install Plugins**.
3.  Search for **"MCD Visualizer"**.
4.  Install the plugin.
5.  On first launch, follow the prompt to select your MCD `data` folder.
