高分辨率动态肢体探测仪(HIRDLS)于2004年7月在NASA Aura卫星上发射。HIRDLS是英国和美国的联合项目，是一个中红外肢体发射探测仪，旨在测量从对流层上层到中间层的地球大气中痕量物种、云和气溶胶的浓度，以及温度和气压的变化。该仪器的目的是在高垂直和水平空间分辨率下进行测量，但验证这些测量是困难的，因为很少有其他测量在时间上提供足够接近的垂直分辨率。然而，FORMOSAT-3/COSMIC系列无线电掩星利用美国GPS发射机获取高分辨率(~1公里)的平流层温度分布，确实提供了与HIRDLS几乎一致的足够分布。比较表明，COSMIC和HIRDLS之间有很好的相关性，分辨率约为2公里，两者的幅度相似，这意味着HIRDLS和COSMIC能够测量相同的小尺度特征。发射期间在HIRDLS内发生的光学阻塞似乎并没有影响这一能力。
The High Resolution Dynamics Limb Sounder (HIRDLS) instrument was launched on the NASA Aura satellite in July 2004. HIRDLS is a joint project between the UK and USA, and is a mid-infrared limb emission sounder designed to measure the concentrations of trace species, cloud and aerosol, and temperature and pressure variations in the Earth's atmosphere from the upper troposphere to the mesosphere. The instrument is intended to make measurements at both high vertical and horizontal spatial resolutions, but validating those measurements is difficult because few other measurements provide that vertical resolution sufficiently closely in time. However, the FORMOSAT-3/COSMIC suite of radio occultation satellites that exploit the U.S. GPS transmitters to obtain high resolution (~1 km) temperature profiles in the stratosphere does provide sufficient profiles nearly coincident with those from HIRDLS. Comparisons show a good degree intercorrelation between COSMIC and HIRDLS down to about 2 km resolution, with similar amplitudes for each, implying that HIRDLS and COSMIC are able to measure the same small scale features. The optical blockage that occurred within HIRDLS during launch does not seem to have affected this capability.
