# WIA-ENE-062: Glacier Preservation
## Phase 3 - Protocol Specification

**Version:** 1.0.0
**Status:** Draft
**Last Updated:** 2025-12-25

---

## Overview

This document defines the communication protocols, monitoring procedures, and operational standards for glacier preservation systems within the WIA-ENE-062 framework.

## Communication Protocols

### 1. Data Transmission Protocol

#### HTTPS/TLS Requirements

All data transmissions MUST use TLS 1.3 or higher:

```
Protocol: HTTPS
TLS Version: >= 1.3
Cipher Suites: TLS_AES_256_GCM_SHA384, TLS_CHACHA20_POLY1305_SHA256
Certificate: Valid X.509 from recognized CA
```

#### Message Format

Standard message envelope for all communications:

```json
{
  "header": {
    "version": "1.0.0",
    "messageId": "uuid-v4",
    "timestamp": "ISO8601",
    "sender": {
      "id": "string",
      "type": "string"
    },
    "recipient": {
      "id": "string",
      "type": "string"
    },
    "priority": "string"
  },
  "payload": {
    "type": "string",
    "data": {}
  },
  "signature": {
    "algorithm": "Ed25519",
    "value": "base64"
  }
}
```

**Priority Levels:**

- `critical`: Immediate processing required (glacier collapse warning)
- `high`: Process within 1 hour (rapid melt event)
- `normal`: Process within 24 hours (regular measurements)
- `low`: Process when convenient (historical data upload)

### 2. Real-Time Monitoring Protocol

#### WebSocket Connection

For continuous monitoring streams:

```
wss://stream.wia.org/glacier-preservation/v1
```

**Connection Headers:**

```
Upgrade: websocket
Connection: Upgrade
Sec-WebSocket-Version: 13
Sec-WebSocket-Protocol: glacier-monitoring-v1
Authorization: Bearer {token}
```

**Message Types:**

```json
{
  "type": "measurement_update",
  "glacierId": "GLR-001-HIM",
  "timestamp": "2025-12-25T10:30:00Z",
  "data": {
    "temperature": -5.2,
    "meltRate": 2.3,
    "albedo": 0.65
  }
}
```

**Heartbeat Protocol:**

Client sends ping every 30 seconds:

```json
{
  "type": "ping",
  "timestamp": "2025-12-25T10:30:00Z"
}
```

Server responds with pong:

```json
{
  "type": "pong",
  "timestamp": "2025-12-25T10:30:01Z",
  "serverTime": "2025-12-25T10:30:01.234Z"
}
```

### 3. Satellite Data Ingestion Protocol

#### Satellite Data Push

Satellite systems push data using this protocol:

```http
POST /ingest/satellite
Content-Type: multipart/form-data
```

**Form Fields:**

```
satellite_id: string (e.g., "SENTINEL-2A")
acquisition_time: ISO8601
scene_id: string
data_type: string (optical/radar/lidar)
file: binary (GeoTIFF/HDF5)
metadata: JSON
checksum: SHA-256
```

**Metadata Example:**

```json
{
  "sensor": "MSI",
  "resolution": 10,
  "cloudCover": 12.5,
  "snowCover": 78.3,
  "processingLevel": "L2A",
  "coverageArea": {
    "glacierIds": ["GLR-001-HIM", "GLR-002-HIM"],
    "boundingBox": {
      "north": 31.0,
      "south": 30.8,
      "east": 79.2,
      "west": 79.0
    }
  }
}
```

#### Data Processing Acknowledgment

```json
{
  "ingestionId": "ING-20251225-001",
  "status": "processing",
  "estimatedCompletion": "2025-12-25T11:00:00Z",
  "priority": "normal"
}
```

## Monitoring Procedures

### 1. Regular Monitoring Schedule

#### Daily Monitoring

For critical glaciers (high population dependency):

```yaml
frequency: daily
time: 14:00 UTC
parameters:
  - surface_temperature
  - melt_rate_estimate
  - albedo
  - weather_conditions
transmission: automatic
storage: 90 days hot, indefinite cold
```

#### Weekly Monitoring

For standard monitoring glaciers:

```yaml
frequency: weekly
day: Sunday
time: 12:00 UTC
parameters:
  - mass_balance
  - surface_area
  - elevation_change
  - debris_coverage
transmission: batch_upload
storage: 365 days hot, indefinite cold
```

#### Seasonal Assessment

For all monitored glaciers:

```yaml
frequency: quarterly
timing:
  - end_of_winter: March 31
  - mid_summer: July 31
  - end_of_summer: September 30
  - mid_winter: December 31
parameters:
  - comprehensive_mass_balance
  - volume_change
  - ice_thickness_grid
  - glacier_boundary
  - equilibrium_line_altitude
transmission: manual_review_then_upload
storage: indefinite
```

### 2. Event-Triggered Monitoring

#### Critical Events

Automatic enhanced monitoring triggered by:

1. **Rapid Melt Event**
   - Threshold: Melt rate > 2x normal
   - Response: Increase to hourly monitoring
   - Duration: Until rate returns to < 1.5x normal

2. **Glacier Lake Outburst Flood (GLOF) Risk**
   - Threshold: Lake volume > critical level
   - Response: Real-time monitoring + visual surveillance
   - Alert: Downstream communities

3. **Temperature Anomaly**
   - Threshold: > 3°C above historical average
   - Response: Daily monitoring + satellite task
   - Duration: Until anomaly < 2°C

4. **Albedo Decrease**
   - Threshold: Albedo drop > 0.1 in 7 days
   - Response: Investigation of debris/soot/algae
   - Action: Imagery analysis + field verification

#### Event Notification Protocol

```json
{
  "eventType": "rapid_melt",
  "glacierId": "GLR-001-HIM",
  "detectedAt": "2025-12-25T10:45:00Z",
  "severity": "high",
  "measurements": {
    "currentMeltRate": 4.8,
    "normalMeltRate": 2.3,
    "ratio": 2.09
  },
  "automatedResponse": {
    "monitoringFrequency": "hourly",
    "satelliteTasking": true,
    "alertsSent": ["downstream_communities", "research_institutions"]
  },
  "recommendedActions": [
    "Verify measurements with alternative sensors",
    "Check weather anomalies",
    "Assess GLOF risk",
    "Notify water resource managers"
  ]
}
```

### 3. Quality Assurance Protocol

#### Data Validation Steps

1. **Automated Validation**
   ```
   Range Check → Consistency Check → Trend Analysis → Outlier Detection
   ```

2. **Manual Review Triggers**
   - Measurement outside 3σ (standard deviations)
   - Sudden change > 50% from previous
   - Inconsistency with satellite observations
   - Sensor malfunction indicators

3. **Validation Workflow**

```mermaid
flowchart TD
    A[Data Received] --> B{Automated Checks}
    B -->|Pass| C[Accept]
    B -->|Fail| D[Flag for Review]
    D --> E{Manual Review}
    E -->|Valid| F[Accept with Annotation]
    E -->|Invalid| G[Reject]

    C --> I[Archive]
    F --> I
    G --> J[Log Error]
    H --> K[Schedule Re-survey]
```

#### Quality Scores

Each measurement receives a quality score (0-1):

```json
{
  "measurementId": "MSR-20251225-001",
  "qualityScore": 0.96,
  "qualityFactors": {
    "instrumentCalibration": 1.0,
    "weatherConditions": 0.9,
    "spatialCoverage": 0.98,
    "temporalConsistency": 0.95,
    "crossValidation": 0.92
  },
  "validationStatus": "approved",
  "reviewer": "automated"
}
```
