As they operate at a distance closer to the earth , they are only capable of taking cloud images of a limited area of the earth each time 由于较接近地球，它们每次只能拍摄到有限区域的云图。相对地球同步气象卫星，极地轨道气象卫星图像的数目较少，范围亦较小。
Compared with the conventional pictures from geostationary satellites , pictures from polar - orbiting satellites have higher resolution because they fly much closer to the earth 由于极地轨道卫星较接近地面，所以拍摄到的云图分辨率比一般大家熟识的地球同步卫星云图为高。
One of the observational channels on the satellites is particularly sensitive to changes in surface temperatures . the images obtained with this channel enable observation of hill fires 由于极地轨道天气卫星其中一观测频道对地面温度的变化较为灵敏，因此它提供的图像能够观察到山火。

With resolution of down to about 1 km , polar - orbiting weather satellites enable good depiction of the structure of tropical cyclones and estimation of their location and strength 由于极地轨道天气卫星云图的分辨率可达约一公里，所以能清楚显示热带气旋的结构，有助估算热带气旋的中心位置和强度。
Noaa and fy - 1 satellites are polar - orbiting meteorological satellites which are operated by the us national oceanic and atmospheric administration and the china meteorological administration respectively Noaa系列及风云- 1系列卫星分别是美国国家海洋及大气管理局和中国气象局的极地轨道气象卫星。
