  • Study on Radar Echo-Filling in an Occlusion Area by a Deep Learning Algorithm
    remote sensing Article Study on Radar Echo-Filling in an Occlusion Area by a Deep Learning Algorithm Xiaoyan Yin 1, Zhiqun Hu 1,2,*, Jiafeng Zheng 1 , Boyong Li 1 and Yuanyuan Zuo 1 1 School of Atmospheric Sciences, Chengdu University of Information Technology, Chengdu 610225, China; [email protected] (X.Y.); [email protected] (J.Z.); [email protected] (B.L.); [email protected] (Y.Z.) 2 State Key Lab of Severe Weather, Chinese Academy of Meteorological Sciences, Beijing 100081, China * Correspondence: [email protected] Abstract: Radar beam blockage is an important error source that affects the quality of weather radar data. An echo-filling network (EFnet) is proposed based on a deep learning algorithm to correct the echo intensity under the occlusion area in the Nanjing S-band new-generation weather radar (CINRAD/SA). The training dataset is constructed by the labels, which are the echo intensity at the 0.5◦ elevation in the unblocked area, and by the input features, which are the intensity in the cube including multiple elevations and gates corresponding to the location of bottom labels. Two loss functions are applied to compile the network: one is the common mean square error (MSE), and the other is a self-defined loss function that increases the weight of strong echoes. Considering that the radar beam broadens with distance and height, the 0.5◦ elevation scan is divided into six range bands every 25 km to train different models. The models are evaluated by three indicators: explained variance (EVar), mean absolute error (MAE), and correlation coefficient (CC).

Similar principle is Light Detection and Ranging (LIDAR) used in ceilometers. So many other similar principles are there with Detection and Ranging (DAR) having the same equation for range measurement. Radar principle is explained in the following figure: The similar principle LIDAR is illustrated below: 1 Range of Radar Radar is an electronic device which is capable of transmitting an electromagnetic signal, receiving back an echo from a target, and determining various things about the target from the characteristics of the received signal. Range is the distance of the target given by the values of c and t , which is explained as h = ct/2 . Milestones of weather radar • 1842 : Doppler effect • 1888: Electromagnetic waves discovered by Hertz • 1922 : Detection of ships by radio waves by Marconi • 1947: The first weather radar in Washington D.C. • 1990: Introduction of Doppler weather radar • 2000: Doppler weather radars in India 2 Electromagnetic wave A wave propagation containing mutually perpendicular electric and magnetic fields perpendicular to the direction of propagation. Light wave is an example of electromagnetic wave Polarisation of radar signal The direction of propagation of electric field in an electromagnetic wave is known as polarisation. Hence an electromagnetic wave used in radar is either horizontally or vertically polarised. S-band Doppler weather radar of IMD is horizontally polarised and C-band is dual polarised (both horizontal and vertical).

  • Chapter 2 Essentials
    Chapter 2 Essentials A brief description of the fundamentals of remote sensing of precipitation by means of radar measurements will be given in the first section of this chapter. Subsequently, the products of the BALTEX radar centre BRDC will be introduced. 2.1 Fundamentals Many publication deals with the fundamentals of radar meteorology. This is the reason, why this section is comparatively short and will introduce only the most important terms, as far as they are indispensable for the understanding of this study. For a more substantial description I wish to refer to basic literature, such as the books of Atlas (1990) and Battan (1973). Precipitation is a generic term for water in solid or liquid form that falls from the sky as part of the weather to the earth’s surface. The precipitation amount, that falls to surface is indeed a two-dimensional representation of a three-dimensional reality above ground. Pre- cipitation in appreciable amounts can be produced by two basic types of mechanism. One is the spontaneous (or free) lifting of humid air, and the other is the forced lifting of humid air. Spontaneous rise are associated with strong up-drafts within convection cells. Free lifting is associated with frontal systems. Radar The term "radar" originally stands for Radio Aircraft Detection and Ranging. This points to the first task of radar in its history, the detection of aircrafts for military use. At- mospheric hydrometeors interfered the beam frequently, so that the possible benefit for me- teorological use was quickly recognised. General speaking, radar is a system, that uses radio waves for positioning of targets in the atmosphere.

This report has been produced without editorial revision by the Secretariat. It is not an official WMO publication and its distribution in this form does not imply endorsement by the Organization of the ideas expressed. FOREWORD The Thirteenth Session of the Commission for Instruments and Methods of Observation (CIMO) recognized the need for training and placed a greater emphasis on these issues as it planned its activities for its 13th Intersessional period. As next generation weather radars system are deployed the need for more in depth training in instrument and platform siting, operation, calibration, lightning safety and maintenance has been requested. Within this document the team of experts from Turkey, led by Mr Büyükbas, provided training materials that address the basic training needs requested by Commission Members. This excellent work will undoubtedly become a useful tool in training staff in many aspects of operating and maintaining weather radar systems. I wish to express our sincere gratitude to Mr Büyükbas and his colleagues in preparing such a fine series of documents.
