[1] It was observed that during peak growing stage all crops ascribed higher Normalized Difference Vegetation Index NDVI values (0. [2] The study of long-term climatic changes is carried out based on the data of the normalized relative vegetation index NDVI, which is a characteristic of phytobiomass and is used to describe the ecological situation, the amount of contamination and productivity of land. [3] These markers were compared to field phenological observations, and to phenological dates derived from various proxies (Normalized Difference Vegetation Index NDVI time-series from Sentinel-2 A and B images, in situ NDVI measurements, Leaf Area Index LAI and litterfall temporal dynamics). [4] The paper presents the results of applying Landsat satellite images to evaluate the Natural Environmental Quality (NEQ) from the integrated index NEQI (Natural Environmental Quality Index) through the calculation of biophysical variables, including vegetation index NDVI, water surface index NDWI, construction index NDBI and land surface temperature LST. [5] The vegetation index NDVI according to NASA data was used to analyze the condition of the vegetation cover in Bulgaria for the years 2000-2020. [6] It was noted that annual average rainfall tended to decrease while annual average temperature and vegetation index NDVI tended to increase. [7] The purpose of the research was to study the effect of mineral fertilizers and plant protection system on the vegetation index NDVI and its seasonal dynamics in agrocenoses of spring barley with overseeding of perennial grasses in the North-West of Russia. [8] Base on the multispectral image and the normalized vegetation index NDVI, we construct a classifier to detect the different growth stage of the fruits by analyzing the color component and using the C4. [9] The practical application of the algorithm has reduced the uncertainty in the vegetation index NDVI by 1. [10] RESULTS Significant differences occurred in the vegetation index NDVI of those sensor levels which were operated inside the winter wheat canopy between plots infected by stripe rust (2018, 2019) and leaf rust (2020). [11] The Normalized difference vegetation index NDVI and the crust index CI were used, which were applied to two of the Landsat ETM + and OLI satellite imagery during the years 1990 and 2019. [12] 4 mm), and the temperature and vegetation index NDVI-to increase (9. [13] Linear regression equations have been obtained, which make it possible to assess the degree of relationship between yield and vegetation index NDVI. [14] Based on Google Earth Engine remote sensing big data cloud computing platform and high spatial and temporal resolution remote sensing image data Sentinel-2, this study takes Kuitun Reclamation Area of the Seventh Division of Xinjiang Production and Construction Corps, a typical cotton growing area in Xinjiang, as an example, and uses continuous time series image data combined with various indices (such as commonly used normalized vegetation index NDVI, normalized moisture index NDWI and cotton chlorophyll data SPAD), a time series analysis model was constructed to analyze the cotton growth conditions in different growing seasons in the study area. [15] The proposed vegetation index NDVI dynamic model allows us to move from describing the plants’ development and growth phenomenological way to model ideas about the vegetation process as a whole. [16] The Normalized Difference Vegetation Index NDVI, Land Surface Water Index LSWI, and Normalized Differential Salinity Index NDSI are used. [17] During the period under consideration, satellite data confirmed the fact that the values of the vegetation index NDVI grew by an average of 12 % in comparison with the average long-term data. [18] UAV vegetation index NDVI (Normalized Difference Vegetation Index) allowed estimation of damages in rice crops at 10 cm pixel resolution by discriminating no-green vegetation pixels. [19] This study adapted and applied the sensible heat flux calibration mechanism of Surface Energy Balance Algorithm for Land (SEBAL) to 16 clear-sky Landsat 7 ETM+ dataset, following a guided automatic pixels search from surface temperature Ts and Normalized Difference Vegetation Index NDVI (). [20] The MLRM established using the vegetation index NDVI may be more applicable to environments where vegetation and salts were doped-together. [21] The process of natural regeneration presented a positive pattern of vegetation expansion in environments under anthropic influence in the Cerrado, which was due to the seasons, time, and climatic elements, and was observed through the temporal dynamics of normalized difference vegetation index NDVI and GPP in the watershed. [22] The variables are: i) 46 Landsat-8 satellite images with less than 10% of cloud cover and some indexes (normalized difference vegetation index NDVI, Soil-adjusted Vegetation Index SAVI, etc. [23] Although the annual maximum ten-day normalized vegetation index NDVI and vegetation coverage in the whole basin over the past more than 10 years did not exhibit significant decline or class difference, there were significant negative temporal correlations of the annual maximum NDVI index and the vegetation coverage with the light intensity in the surrounding area and the corridors of main communication. [24] Decoding was carried out on ENVI software package; to assess the change in vegetation state, vegetation index NDVI was used. [25]주파수 채널의 신호는 정규화된 차이 식생 지수 NDVI, 지표면 LSWI의 수분 지수를 결정하는 데 사용됩니다.
