Variable Units Dictionary

Below is a simple example of how you could define a C# Dictionary<string, string> to map each variable to its typical meteorological/soil-measurement units. (Of course, exact units can vary depending on your instrumentation or regional conventions.)

using System;
using System.Collections.Generic;

public class Program
{
    public static void Main()
    {
        // Dictionary mapping variable names to units
        Dictionary<string, string> variableUnits = new Dictionary<string, string>()
        {
            { "Air Temperature",    "°C"       },  // or °F, depending on region
            { "Solar Radiation",    "W/m²"     },  // often reported in W/m²
            { "Precipitation",      "mm"       },  // could be mm or inches
            { "Wind Direction",     "°"        },  // degrees from North
            { "Wind Speed",         "m/s"      },  // could be m/s, km/h, or mph
            { "Gust Speed",         "m/s"      },  // same as Wind Speed units
            { "VPD",                "kPa"      },  // Vapor Pressure Deficit
            { "Leaf Wetness Level", "dimensionless" },  // or 0–15 scale, depending on sensor
            { "Water Content",      "m³/m³"    },  // volumetric water content
            { "Soil Temperature",   "°C"       },  // or °F
            { "Matric Potential",   "kPa"      }   // could also be MPa or bars
        };

        // Example usage:
        foreach (var kvp in variableUnits)
        {
            Console.WriteLine($"Variable: {kvp.Key}, Unit: {kvp.Value}");
        }
    }
}

Notes on units

Air Temperature: Commonly reported in Celsius (°C) or Fahrenheit (°F).
Solar Radiation: Often reported in watts per square meter (W/m²). Some sensors or datasets may use other units like MJ/m².
Precipitation: Commonly millimeters (mm) or inches.
Wind Direction: Typically degrees (°) clockwise from North (0–360).
Wind Speed / Gust Speed: Could be meters per second (m/s), kilometers per hour (km/h), or miles per hour (mph), depending on locale.
VPD (Vapor Pressure Deficit): Often in kilopascals (kPa).
Leaf Wetness Level: Many leaf-wetness sensors output a 0–15 scale (dimensionless).
Water Content (Soil Moisture): Often given as volumetric water content (m³/m³), which can also be expressed as a percentage (%).
Soil Temperature: Same as air temperature (°C or °F).
Matric Potential: Commonly in kilopascals (kPa) or bars; sometimes reported in MPa.

Adjust these mappings to match the exact conventions and sensors used in your application.
