Comparison between early Odin-SMR, Aura MLS and CloudSat retrievals of cloud ice mass in the upper tropical troposphere
Emerging microwave satellite techniques are expected to provide improved global measurements of cloud ice mass. CloudSat, Aura MLS and Odin-SMR fall into this category and early cloud ice retrievals from these instruments are compared. The comparison follows the SMR retrieval product and is made for partial ice water columns above 12 km. None of the retrievals shows a significant degree of fals...
متن کاملIntercomparisons Between Remote and In Situ Measurements of Ice Cloud Microphysics During the Spring 1997 Cloud IOP
The spring 1997 Cloud Intensive Observation Period (IOP) was conducted at the Southern Great Plains (SGP) Cloud and Radiation Testbed (CART) site during April 1997. The objectives of this IOP included comprehensive testing of the Atmospheric Radiation Measurement (ARM) Program’s millimeter-wave cloud radar (MMCR) and verifications of several cloud retrieval algorithms by comparisons of the remo...
متن کاملFirst Odin sub-mm retrievals in the tropical upper troposphere: humidity and cloud ice signals
Odin-SMR is a limb-sounder operating in the 500 GHz region with the capability of performing measurements down to altitudes of about 10 km with relatively low influence of ice clouds. Until now spectra from tropospheric tangent altitudes have been disregarded due to inadequate handling of scattering. A first method to extract upper tropospheric quantities has now been developed, yielding the hu...
متن کاملCirrus cloud susceptibility to the injection of ice nuclei in the upper troposphere
Due to their net warming effect, cirrus clouds play a crucial role in the climate system. A recently proposed climate engineering mechanism (CEM) intends to reduce high cloud cover by seeding cirrus clouds with efficient ice nuclei (IN) and therefore cool climate. Here, the susceptibility of cirrus clouds to the injection of ice nuclei in the upper troposphere is investigated in the extended Co...
متن کاملInteractive comment on “Comparison between the first Odin-SMR, Aura MLS and CloudSat retrievals of cloud ice mass in the upper tropical troposphere” by P. Eriksson et al
The results in the manuscript are formally correct, but we have anyhow decided to make a complete revision of the manuscript using newer data versions. In the preparation of another manuscript (at the Chalmers University) it was found that the used CloudSat retrieval version, R03, gives a biased view of the mean ice mass in the studied part of the atmosphere. The official CloudSat retrievals ar...
