UK Marine Surface Observations

# Overview

This data product includes marine surface weather observations for 31 parameters from 69 locations. The observations are produced and transmitted to Snowflake every hour.

## About the marine observation network

This listing includes data from moored buoys, light vessels and ships with automatic weather stations onboard. Buoys and light vessels are static and you can view their locations on the [Met Office Marine Observations page](https://weather.metoffice.gov.uk/specialist-forecasts/coast-and-sea/observations). Other marine observations network data sources that are not included in this listing include third-party offshore installations, drifting buoys, Argo floats, marine gliders and voluntary observing ships with manual data submission.

## How the data is produced

Each observation location produces data at hourly intervals. Measurements are converted to standard meteorological formats before rigorous checks verify the integrity of the data. The data is then transmitted to users worldwide.

Periods of missing data may be due to:

- Scheduled maintenance of observation instrumentation
- Unexpected issues with instrumentation, sensor failure or network disruption
- Ships being in port

Such issues may cause delays in data being transmitted. If this happens, we will try to retrieve observations for up to the past 24 hours to provide as complete a dataset as possible.

## Parameters

31 individual meteorological parameters are measured across the observation network. Not all locations record all parameters. Broadly speaking, the following observation location types report the following parameters:

- Buoys collect up to 28 parameters across different groupings:
- Air pressure
- Air temperature
- Dew point temperature
- Relative humidity
- Sea surface temperature
- Significant wave height
- Wave height
- Wave direction
- Wave period
- Wind direction
- Wind gust
- Wind speed
- Light Vessels
- Air pressure
- Air temperature
- Dew point temperature
- Visibility
- Relative humidity
- Sea surface temperature
- Significant wave height
- Wave period
- Wind direction
- Wind gust
- Wind speed
- Shipping
- Air pressure
- Air temperature
- Dew point temperature
- Relative humidity

A full list of parameters, including descriptions and units of measure is available in the *MARINE_PARAMETER_METADATA* view.

## Update frequency and latency

Every hour, at 15 minutes past the hour, we retrieve a single set of parameter values for each location. For example, at 12:15 new data is retrieved for observations collected between 11:00 and 12:00. This is due to the quality checks required to verify data for public consumption and global network latency.

## Archive length

Observations are available for a rolling 7-day period (168 hours).

UK Marine Surface Observations 数据集概述

数据集基本信息

• 数据集名称: UK Marine Surface Observations
• 提供商: Met Office
• 数据集地址: https://app.snowflake.com/marketplace/listing/GZTDZ43BT3QL

数据内容描述

• 数据内容: 包含来自英国气象局海洋观测网络69个站点的海面天气观测数据。
• 观测网络构成: 数据来源于系泊浮标、灯船以及配备自动气象站的船舶。不包括第三方海上设施、漂流浮标、Argo浮标、海洋滑翔机和手动提交数据的志愿观测船。
• 观测参数: 共31个气象参数，不同站点记录的参数不同。
  • 浮标: 最多收集28个参数，包括气压、气温、露点温度、相对湿度、海面温度、有效波高、波高、波向、波周期、风向、阵风、风速等。
  • 灯船: 收集参数包括气压、气温、露点温度、能见度、相对湿度、海面温度、有效波高、波周期、风向、阵风、风速。
  • 船舶: 收集参数包括气压、气温、露点温度、相对湿度。
• 参数详情视图: 完整的参数列表、描述和计量单位可在 MARINE_PARAMETER_METADATA 视图中查看。
• 主要数据视图: MARINE_OBSERVATIONS_DATA_7_DAY_VIEW。

数据生产与更新

• 生产频率: 每个观测站点每小时产生一次数据。
• 数据处理: 测量值在传输前会转换为标准气象格式并经过严格检查。
• 更新频率与延迟: 每小时（在整点过15分钟）检索一次每个站点的参数值集。例如，12:15检索的是11:00至12:00期间收集的观测数据。延迟源于数据质量检查和全球网络延迟。
• 数据缺失原因: 可能由于观测仪器的计划维护、仪器意外问题（传感器故障或网络中断）或船舶在港。
• 数据补全: 若发生延迟，会尝试检索过去24小时内的观测数据以提供尽可能完整的数据集。

数据存档与覆盖范围

• 存档长度: 提供滚动7天（168小时）的观测数据。
• 时间覆盖: 最近7天，按小时。
• 地理覆盖: 英国，按经纬度。

数据用途

• 现实世界数据: 对于需要准确海洋天气记录以辅助决策的行业（如航运和海上能源）至关重要，也用于评估海洋天气预报的准确性。
• 态势感知: 可用于评估最新天气对海洋地点的影响。
