The radar echo map extrapolation plays a vital role in this task. Recently, deep learning techniques such as Convolutional Recurrent Neural Network (ConvRNN) models have been designed to solve the task. These models, albeit performing much better than conventional optical flow based approaches, suffer from a common problem of underestimating the high echo value parts. The drawback is fatal to precipitation nowcasting, as the parts often lead to heavy rains that may cause natural disasters. In this paper, we propose a novel interaction dual attention long short-term memory (IDA-LSTM) model to address the drawback. In the method, an interaction framework is developed for the ConvRNN unit to fully exploit the short-term context information by constructing a serial of coupled convolutions on the input and hidden states. Moreover, a dual attention mechanism on channels and positions is developed to recall the forgotten information in the long term. Comprehensive experiments have been conducted on CIKM AnalytiCup 2017 data sets, and the results show the effectiveness of the IDA-LSTM in addressing the underestimation drawback. The extrapolation performance of IDA-LSTM is superior to that of the state-of-the-art methods.<\/jats:p>","DOI":"10.3390\/rs13020164","type":"journal-article","created":{"date-parts":[[2021,1,6]],"date-time":"2021-01-06T20:45:42Z","timestamp":1609965942000},"page":"164","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":51,"title":["A Novel LSTM Model with Interaction Dual Attention for Radar Echo Extrapolation"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4848-609X","authenticated-orcid":false,"given":"Chuyao","family":"Luo","sequence":"first","affiliation":[{"name":"The Department of Computer Science, Harbin Institute of Technology, Shenzhen 518055, China"}]},{"given":"Xutao","family":"Li","sequence":"additional","affiliation":[{"name":"The Department of Computer Science, Harbin Institute of Technology, Shenzhen 518055, China"}]},{"given":"Yongliang","family":"Wen","sequence":"additional","affiliation":[{"name":"The Department of Computer Science, Harbin Institute of Technology, Shenzhen 518055, China"}]},{"given":"Yunming","family":"Ye","sequence":"additional","affiliation":[{"name":"The Department of Computer Science, Harbin Institute of Technology, Shenzhen 518055, China"}]},{"given":"Xiaofeng","family":"Zhang","sequence":"additional","affiliation":[{"name":"The Department of Computer Science, Harbin Institute of Technology, Shenzhen 518055, China"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"165","DOI":"10.1175\/1520-0469(1948)005<0165:TDORWS>2.0.CO;2","article-title":"The distribution of raindrops with size","volume":"5","author":"Marshall","year":"1948","journal-title":"J.
