CERES Time-Interpolated TOA Fluxes, Clouds and Aerosols Monthly Aqua Edition4A

CER_SSF1deg-Month_Aqua-MODIS_Edition4A is the Clouds and the Earth's Radiant Energy System (CERES) Time-Interpolated Top of Atmosphere (TOA) Fluxes, Clouds and Aerosols Monthly Aqua Edition4A data product, which was collected using the CERES Flight Model 3 (FM3) and FM4 instruments on the Aqua platform. Data collection for this product is in progress.

CERES Single Scanner Footprint One Degree (SSF1deg) Day provides daily averages of regional constant meteorology temporally interpolated TOA fluxes, clouds derived from a co-located imager, and aerosols on a 1-degree latitude and longitude grid. This single satellite product uses the primary CERES instrument in cross-track mode. TOA fluxes are provided for clear-sky and all-sky conditions for longwave (LW), shortwave (SW), and window (WN) wavelength bands. The incoming solar daily irradiance is from the SOlar Radiation and Climate Experiment (SORCE) and Total Solar Irradiance (TSI). The cloud properties are averaged for day and night (24-hour) and day-only periods. Cloud properties are stratified into four atmospheric layers (surface-700 hPa, 700 hPa, - 500 hPa, 500 hPa, - 300 hPa, 300 hPa, - 100 hPa) and a total of all layers. The aerosols are averaged instantaneous values from the co-located imager.

CERES is a key Earth Observing System (EOS) program component. The CERES instruments provide radiometric measurements of the Earth's atmosphere from three broadband channels. The CERES missions follow the successful Earth Radiation Budget Experiment (ERBE) mission. The first CERES instrument, the protoflight model (PFM), was launched on November 27, 1997, as part of the Tropical Rainfall Measuring Mission (TRMM). Two CERES instruments (FM1 and FM2) were launched into polar orbit on board the Earth Observing System (EOS) flagship Terra on December 18, 1999. Two additional CERES instruments (FM3 and FM4) were launched on board Earth Observing System (EOS) Aqua on May 4, 2002. The CERES FM5 instrument was launched on board the Suomi National Polar-orbiting Partnership (NPP) satellite on October 28, 2011. The newest CERES instrument (FM6) was launched on board the Joint Polar-Orbiting Satellite System 1 (JPSS-1) satellite, now called NOAA-20, on November 18, 2017.

CER_SSF1deg-Month_Aqua-MODIS_Edition4A 是云和地球辐射能量系统（Clouds and the Earth's Radiant Energy System, CERES）时间插值大气顶（Top of Atmosphere, TOA）通量、云与气溶胶月度Aqua第4A版数据产品，其数据由Aqua平台上的CERES飞行模型3（Flight Model 3, FM3）与FM4仪器采集，当前该产品的数据采集工作仍在进行中。

CERES单扫描仪足迹1度网格（Single Scanner Footprint One Degree, SSF1deg）日数据集提供了经时间插值得到的、对应区域恒定气象条件的TOA通量、同位成像仪反演得到的云属性，以及1度经纬度网格上的气溶胶的日平均值。该单卫星数据集采用跨轨扫描模式下的主CERES仪器进行观测。TOA通量涵盖晴空与全天空条件下的长波（LongWave, LW）、短波（ShortWave, SW）与窗口（Window, WN）波段。入射太阳日辐照度数据来自太阳辐射与气候实验卫星（SOlar Radiation and Climate Experiment, SORCE）与总太阳辐照度（Total Solar Irradiance, TSI）。云属性分别按昼夜（24小时）与仅日间时段取平均。云属性被划分为四个大气层（地表-700百帕、700-500百帕、500-300百帕、300-100百帕）以及所有大气层总和的层级。气溶胶数据为同位成像仪获取的瞬时值的平均值。

CERES是地球观测系统（Earth Observing System, EOS）计划的核心组成部分。CERES仪器通过三个宽带通道对地大气进行辐射测量。CERES任务接续已圆满完成的地球辐射预算实验（Earth Radiation Budget Experiment, ERBE）任务。首台CERES仪器为原型飞行模型（protoflight model, PFM），作为热带降雨测量任务（Tropical Rainfall Measuring Mission, TRMM）的载荷于1997年11月27日发射升空。两台CERES仪器（FM1与FM2）作为地球观测系统（EOS）旗舰卫星Terra的载荷，于1999年12月18日被送入极地轨道。另外两台CERES仪器（FM3与FM4）于2002年5月4日搭载地球观测系统（EOS）Aqua卫星发射升空。CERES FM5仪器于2011年10月28日搭载苏奥米国家极地轨道伙伴卫星（Suomi National Polar-orbiting Partnership, NPP）发射升空。最新的CERES仪器（FM6）于2017年11月18日搭载联合极地卫星系统1号（Joint Polar-Orbiting Satellite System 1, JPSS-1，现更名为NOAA-20）卫星发射升空。
