1. What does Remote Sensing Systems offer?

Remote Sensing Systems (RSS) is a world leader in processing and analyzing microwave data collected by satellite microwave sensors. We provide research-quality geophysical data to the global scientific community.了解更多关于我们的信息。

2.遥感什么?

遥感,因为它涉及我们在遥感系统的研究中,是指使用距离地球轨道的距离制成的观察万博网址是什么。万博体育app网页注册这些卫星设计用于在电磁谱中观察特定波长或频率的地球。在遥感万博体育app网页注册系统中,我们主要使用来自电磁频谱的微波区域的卫星数据。

微波是一种由地球和大气发出和反射的电磁辐射。微波辐射与大气相互作用。上面的电磁谱图显示了微波在无线电/电视和红外辐射之间的频率。许多类型的遥感仪器测量微波。我们在遥感系统的三种类型中处理数据:辐射仪,散射仪和发声器。万博体育app网页注册

辐射计(1Manbetx ,2018世界杯狗万滚球app ,AMSR,amsr2.,2019新万博appmanbetⅩ ,GMI)通过从地球表面自然发射的微波辐射。不同量的辐射从陆地表面与水面发射。在海洋中,辐射转移模型和物理算法用于检索地球物理参数:表面风速,大气柱状水蒸气,云液体水,雨率和海表面温度。为了测量海表面温度,需要较低的频率测量。万博吧manbet客户端2.0并非所有辐射仪都可以测量较低的频率。

Scatterometers (NSCAT,QuikSCAT,1mantbex )是活动的微波仪器,其向地球表面发出微波脉冲并测量反射/返回的能量。地球物理模型功能用于从返回的能量中提取表面风速和方向。

探测器(MSU,AMSU) make use of multiple channels and frequencies to measure the microwave radiation originating from different heights in the atmosphere. Using a weighting function, microwave sounder data can be used to determine the atmospheric temperature for these heights in the atmosphere, effectively creating an atmospheric profile of temperature.

4. Which data set should I use?

为了选择相应的数据集,首先评估您的研究需求。万博网址是什么

  • Do you need the most accurate, unprocessed data? [use daily files or orbit files if available]
  • Do you need a complete map with no data gaps? [use 3-day, weekly files, or merged data files]
  • What time frame do you need (daily, weekly, longer)?
  • Do you need precise measurements or could your result be obtained via averaged data (either in time or space)? [use daily for precise measurements, merged data or averaged data otherwise]
  • Are you interested in data from a specific instrument or do you require a parameter measurement blended from multiple satellites? [access instrument files or use a merged product]
  • Does your research require climate-quality, error-assessed data? [use the monthly, 1-deg data]

Once you have determined your research needs, check out ourData Accesspage.

5. What data formats are available from Remote Sensing Systems?

The microwave products listed in the last column of the table above are available as raw binary data files (just the data, no headers, metadata or special formatting). NetCDF files (a self-describing format with metadata) are available at NASA data archive centers. For QuikSCAT, NSCAT, and ASCAT we provide orbital files (one orbit of data per file) as well as gridded daily, 3-day, weekly, or monthly files (orbital data mapped to a 0.25 deg grid). Special climate summary files are also available for some geophysical parameters. Descriptions of the data products are available on themissions或者1manbext web pages and included links.

6. Where can I get Remote Sensing Systems data?

Data files are available from Remote Sensing Systems byFTP或者HTTP. See theData Access表格为各种文件的特定链接。你将首先需要注册帐户以便通过FTP访问数据。一些NASA数据存档中心还提供数据,并可提供额外的可视化工具或资源。

7.如何在下载之前查看数据?

可以使用我们的Web浏览环境查看在遥感系统上开发的大多数数据产品万博体育app网页注册:SSMI/SSMIS,TMI.,AMSR-E.,amsr2.,风Sat,GMI,QuikSCAT, andascat.. The browse environment displays pre-rendered maps of data. If you find a specific image for which you would like to download the data file, click on the Get Data button within the browse environment.

8. How do I read the data?

For the binary data provided by Remote Sensing Systems there are read routines in IDL, Fortan-90, Matlab, C++ and Python located in the support directories under each instrument on ourFTPHTTPdata servers. These read routines can be augmented to suit your processing needs. Verify text files are provided to ensure proper reading of the data after altering the read routine. Please be sure to check that the verify text file matches your output before contacting us with questions. All read routines have been tested on Windows machines with IDL 8.2, Intel Visual Fortran-90 compiler, Matlab r2014a, Intel C++ XE 2011, and Python 2.7 on Windows machines. NetCDF data files can also be accessed using many of the visualization tools publicly available.
