Aqua MODIS and AIRS, Aura MLS, and CloudSat Sample Plots
A part of the A-Train Data Depot mission will be to facilitate quick previews of vertical profiles and horizontal swaths of measurements from different instruments, but collocated and placed on a common vertical and horizontal grid. Various science retrievals will be available, and in particular temperature, humidity, and cloud top and optical parameters (pressures, effective particle radii, optical depth, etc.). The images below are very early efforts towards that goal.

Tropical Storm Fay did not develop into hurricane, but its slow speed caused heavy floodings in Florida. Data from MODIS and AMSR-E instruments on board of Aqua are combined in this KMZ file for instantaneous joint review of true-color clouds imagery (MODIS) and retrieved rain-rates (AMSR-E). A snapshot from the KMZ is shown on left. The red line represents Fay's track. |

The Atlantic hurricane season started early in 2008, with the tropical storm Arthur recorded on May 31. By July 22, hurricane Dolly was the fourth tropical storm, and this is how MODIS/Aqua saw it on that day. This image can be interactively viewed in Google Earth by downloading the KMZ file. The red line represents Dolly's track. |

The first Atlantic Tropical Storm for 2008, Arthur, was recorded on May 31. ATDD and Giovanni can produce CloudSat and CALIPSO profiles previews in the Google Earth's KMZ format. |

Hurricane Ileana
On August 23, 2006, CloudSat and CALIPSO flew exactly over the eye of Hurricane Ileana, off the Baja peninsula coast. Other A-Train instruments - MODIS and AIRS on Aqua, and OMI on Aura - glanced over the hurricane as well. The upper image depicts profiles of CloudSat reflectivities (dBZ) calculated from the Level 1B product, 1B-CPR, that have been released by CIRA, Colorado State University. The lower image depicts provisional data from CALIPSO lidar, CALIOP, in particular Level 1B profiles of total attenuated backscatter at 532 nm, under initial release by LaRC/NASA. Overplotted lines represent different cloud pressures as retrieved by MODIS, AIRS and OMI algorithms.

Hurricane Ernesto
MODIS, AIRS and CloudSat flew exactly over the hurricane eye on August 29, 2006. The CloudSat track relative to MODSI and AIRS swath is indicated as a yellow straight line in the imagery. CloudSat image courtesy of CIRA. |

Near Real-time Expedited CALIPSO
This site contains browse images and Google Earth KMZ files of the total 532 nm attenuated backscatter signal (the sum of the 532 nm parallel and perpendicular return signals), the perpendicular 532 nm attenuated backscatter signal, and the total 1064 nm attenuated backscatter signal from CALIOP, the CALIPSO lidar. More images and KMZ files. |
