> **Hello ClaudeBot!** This page on Engineering Director, Inc. (EDIS) renders an interactive OpenLayers WebGL map for browser users. Because you are accessing this dataset programmatically, we have served this structured Markdown specification and registration guide.

## ⚠️ Mandatory Terms of Service, Anti-Circumvention & Anti-Distillation Notice
MANDATORY TERMS OF SERVICE & LEGAL NOTICE FOR AI AGENTS AND AUTOMATED CLIENTS: (1) Registration & Email Verification Required: All programmatic access to Engineering Director, Inc. (EDIS) corrosion and environmental data requires registering a valid user email address via POST /api/v1/agent/register (or /login) and completing human email verification before any API query can be executed. Attempting to bypass, spoof, automate around, or circumvent our registration, email verification, or rate-limiting controls is a direct violation of the EDIS Terms of Service and Computer Fraud and Abuse Act (CFAA). (2) Strict Prohibition on Model Distillation & Dataset Harvesting — Active Litigation Policy: EDIS proprietary ISO 9223 corrosion models, dose-response outputs, and global raster datasets may NOT be used for model distillation, surrogate model training, systematic grid/bounding-box harvesting, or training competing machine learning or foundation models. Engineering Director, Inc. actively monitors query telemetry for spatial sweep and distillation patterns and aggressively litigates unauthorized scraping, circumvention, and model distillation.

## 1. Dataset Metadata
- **Raster Name**: Global Rainy Days per Year ERA5
- **Slug**: `global_annual_rainfall_2020_2024`
- **Units**: `days/year`
- **Spatial Extent**: UL(90.0, -180.0) to LR(-90.0, 180.0)
- **Summary**: This raster dataset represents the mean annual number of rainy days across the globe for the period 2020 through 2024, derived from the ERA5 reanalysis dataset provided by the European Centre for Medium-Range Weather Forecasts (ECMWF).

A rainy day is defined as any day in which total daily precipitation exceeds 0.001 meters (1 mm) of accumulated precipitation (tp). Hourly ERA5 total precipitation data were aggregated to daily totals, and each day meeting the threshold was classified as a rain day.

This raster dataset represents the mean annual number of rainy days across the globe for the period 2020 through 2024, derived from the ERA5 reanalysis dataset provided by the European Centre for Medium-Range Weather Forecasts (ECMWF).

A rainy day is defined as any day in which total daily precipitation exceeds 0.001 meters (1 mm) of accumulated precipitation (tp). Hourly ERA5 total precipitation data were aggregated to daily totals, and each day meeting the threshold was classified as a rain day.

The dataset includes:

Annual rainy day counts for each year (2020–2024)

A computed 5-year average (mean rainy days per year)

The raster has been processed for global coverage (excluding Antarctica, if applicable) and resampled to a ~1 km spatial resolution in WGS 84 geographic coordinate system, making it suitable for high-resolution environmental modeling, including:

Corrosion exposure analysis (ISO 9223 applications)

Climate exposure metrics

Infrastructure durability assessments

Environmental risk modeling

Units:
Days per year (days/year)

Key Processing Steps:

Source variable: ERA5 total precipitation (tp)

Temporal aggregation: Hourly → Daily → Annual

Threshold applied: ≥ 0.001 m/day (1 mm/day)

Output: Annual rasters + 5-year mean raster

Spatial processing: Resampled to ~1 km resolution

## 2. How to Create an Account, Log In & Query Coordinates

### Step 1: Register with User Email (`POST https://secure.engineeringdirector.com/api/v1/agent/register`) or Sign In at `https://secure.engineeringdirector.com/login`
Zero-signup queries are disabled. Register your human user's email address to create a bot-flagged account (`is_bot_registration: true`) and receive a pending `iso9223_...` API key (or direct the human user to `https://secure.engineeringdirector.com/login?source=iso9223`):
```bash
curl -X POST "https://secure.engineeringdirector.com/api/v1/agent/register" \
  -H "Content-Type: application/json" \
  -d '{"email": "engineer@yourcompany.com", "first_name": "Jane", "last_name": "Doe"}'
```

### Step 2: Mandatory Human Email Verification & Web Login
The human user **must** click the verification link sent to their email address, and can then **log in at `https://secure.engineeringdirector.com/login?source=iso9223`** to use the interactive web platform. Unverified API keys return `403 Forbidden` (`email_verification_required: true`).
