Remote sensing combined with CASA (Carnegie\u2013Ames\u2013Stanford Approach) model is a mainstream method to calculate the NPP, which is generally based on the ENVI or ArcGIS in the standalone mode. However, with the enhancement of spatial and temporal resolution of remote sensing images, the volume of data has also grown rapidly, which makes the centralized methods not well adapted to the NPP calculation. In this paper, we propose SCASA, a Spark-based parallel approach for NPP calculation with CASA model. Based on the distributed storage characteristics of HDFS, we propose a storage strategy specifically for CASA model. Based on the characteristics of CASA model and Spark\u2019s parallel computing rules, we redesign the computation process to maximize parallelism to further improve the calculation speed. Extensive comparative experiments based on ArcGIS and Spark demonstrate the proposed approach outperform the existing CASA model. <\/jats:p>","DOI":"10.1142\/s0218126622502449","type":"journal-article","created":{"date-parts":[[2022,4,28]],"date-time":"2022-04-28T10:23:06Z","timestamp":1651141386000},"source":"Crossref","is-referenced-by-count":1,"title":["SCASA: A Spark-Based Parallel Approach for Net Primary Productivity Calculation with CASA Model"],"prefix":"10.1142","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0152-2594","authenticated-orcid":false,"given":"Hui","family":"Zhang","sequence":"first","affiliation":[{"name":"College of Meteorology and Oceanography, National University of Defense Technology, Changsha, P.
