Evaluation method of near space atmospheric environment data

The invention discloses a near space atmospheric environment data evaluation method. The method comprises the following steps: acquiring original data of a near space atmospheric environment; preprocessing the original data to obtain preprocessed data; establishing a near space atmospheric change range based on the preprocessed data, and screening and judging the preprocessed data based on the near space atmospheric change range to obtain effective data; performing gridding processing on the effective data to obtain a test data source; and inputting an evaluation object, matching the evaluation object with the test data source based on a principle of proximity matching to obtain a matching result, and testing and evaluating the matching result. According to a large amount of observation data statistical results, the threshold range of near space temperature, density, air pressure, weft wind, warp wind, wind speed and wind direction is reasonably formulated. The method is suitable for evaluating near space atm
