Introduction

Global climate variability, environmental change, and extreme weather events increasingly demand reliable, high-resolution environmental monitoring tools. As a PhD Candidate at UC Davis specializing in remote sensing, climate analytics, and AI for environmental applications, I mentored my undergraduate mentee, through an ambitious project: building an interactive, global-scale environmental monitoring portal powered by Google Earth Engine (GEE).

Together, we developed the Global Vegetation and Climate Insights Portal (GVCIP)—a web application that visualizes global vegetation health, land surface temperature, evapotranspiration, precipitation, and more. My mentee successfully presented this project at the UC Davis College of Engineering, where both of us received certificates for our contributions.

This blog post highlights the project goals, features, methodology, poster, and our presentation.

Project Overview

Project Title: Global Vegetation and Climate Insights Portal (GVCIP): A Google Earth Engine–Based Monitoring Tool

Authors: Nicholas Richmond, Mohammadreza Narimani, Ali Moghimi, Alireza Pourreza

Affiliation: Digital Agriculture Laboratory, UC Davis

The GVCIP portal uses MODIS, Sentinel, and ERA5 datasets within GEE to provide global, interactive maps of key environmental indicators, including:

  • NDVI (Normalized Difference Vegetation Index)
  • Evapotranspiration (ET)
  • Land Surface Temperature (LST)
  • Leaf Area Index (LAI)
  • Fraction of Photosynthetically Active Radiation (FPAR)
  • Mean 2-meter Air Temperature (ERA5)
  • Total Daily Precipitation (ERA5)
āœ”ļø This makes it a powerful resource for researchers, farmers, educators, policymakers, and climate analysts.

Mentoring the Project

Mentoring my undergraduate student on this project involved guiding them through:

  • Understanding remote sensing datasets (MODIS, ERA5, Sentinel)
  • Learning Earth Engine JavaScript programming
  • Designing interactive UI elements (dropdown menus, map layers, charts)
  • Implementing time-series extraction
  • Creating data legends and visualization styles
  • Developing and deploying the web app
  • Writing the full research poster
  • Presenting at the UC Davis ESEARCH and COE events

My mentee showed exceptional dedication and creativity, and I am proud to highlight their work here.

Key Features of the Portal

1ļøāƒ£ Interactive Global Environmental Mapping

Users can explore global datasets with smooth map visualization, zooming, and clicking to retrieve time-series data.

2ļøāƒ£ Dynamic Data Layer Selection

Switch between NDVI, LST, ET, precipitation, vegetation indexes, and more.

3ļøāƒ£ Time-Series Chart Extraction

Click any location on the map to visualize the full year's data trend.

4ļøāƒ£ Automated Scaling & Color Legend

The legend updates based on the dataset selected, providing accurate interpretation.

5ļøāƒ£ Region-Specific Environmental Analysis

Analyze climate and vegetation conditions for any country, region, or pixel.

Methodology Overview

According to the project poster:

1. Dataset Selection

  • MODIS for NDVI, LAI, FPAR, ET, and LST
  • ERA5 for temperature and precipitation

These datasets provide high spatial and temporal resolution, essential for environmental monitoring.

2. Visualization & Mapping

Each environmental indicator is mapped using custom visualization parameters for clarity and consistency.

3. Time-Series Analysis

The app fetches year-long data for any clicked pixel, generating a plot for insights into seasonal changes.

4. User-Friendly Interface

A clean GEE-based UI ensures ease of use for both technical and non-technical audiences.
