Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard was proposed by the China Meteorological Administration. This standard is under the jurisdiction of the National Meteorological Disaster Prevention and Reduction Standardization Technical Committee (SAC/TC345). This standard was drafted.

Introduction

In July.1994, the World Meteorological Organization (WMO) developed an internationally unified representation of the UV Index. World Health Organization.2002 (WHO), World Meteorological Organization (WMO), United Nations Environment Programme (UNEP) and International Commission on Non-Ionizing Radiation Protection (ICNIRP) jointly developed the "Global Solar UV Index. A Practical Guide", the guidelines for UV index, UV influence factors, purple The effects of the external line on the human body and the UV defense measures are described in detail. Many countries adopt the Global Solar UV Index. Practice The Guide conducts UV index forecasting. In order to fully link the "Global Solar UV Index. A Practical Guide" to promote the scientific development of China's ultraviolet forecast, this standard is specially formulated to Guide the UV index forecast. UV index prediction method

1 Scope

This standard specifies the UV index prediction method based on cloud amount, weather phenomenon and surface albedo correction for ground UV irradiance. This standard applies to the UV index forecasting work and related scientific research.

2 Terms and definitions

The following terms and definitions apply to this document. 2.1 Solar ultraviolet solarultraviolet; UV Solar radiation in the solar spectrum with a wavelength range of 100 nm to 400 nm, referred to as ultraviolet light. Note. The solar ultraviolet light can be divided into three bands according to the biological action of different wavelengths. See Appendix A for details. 2.2 Ultraviolet (line) irradiance UVirradiance The solar ultraviolet radiation power received per unit area. Note. The unit is watts per square meter (W/m2). [QX/T 87-2008, Definition 3.2] 2.3 Ultraviolet (line) index UVindex; UVI A quantitative indicator of the effective irradiance level of erythema on the surface of the sun's ultraviolet radiation. [GB/T 21005-2007, definition 3.10] Note 1. The UV index is used to measure the extent of possible damage to human skin, eyes and other tissues and organs by the ultraviolet radiation at the strongest moment of sunshine. purple The larger the external line index, the more serious the damage to the human body. Note 2. See Appendix B for the classification of UV index.

3 Index forecasting method

3.1 UV index calculation For the calculation of the UV index, see equation (1). IUV ≈ Quv·Cer ΔI (1) In the formula. IUV---UV index forecast value, dimensionless value, non-zero integer, rounded up to get; Quv---ground ultraviolet irradiance forecast value in watts per square meter (W/m2); Cer---equivalent erythema correction factor, value 0.01; ΔI---the ultraviolet irradiance equivalent to the unit ultraviolet index, which is 0.025 W/m2. ......
