| Abstract |
The H2O Antarctica Microwave Stratospheric and Tropospheric Radiometers (HAMSTRAD) 183-GHz radiometer has been developed to measure vertical profiles of tropospheric water vapor above Dome C (Concordia station), Antarctica ( 75?06'S, 123?21'E, 3233 m asml), which is an extremely cold and dry environment, over decades. Prior to its installation at Dome C in January 2009, the instrument was deployed at the Pic du Midi (PdM) station ( 42?56'N, 0?08'E, 2877 m asml) in the Pyrenees Mountains, France, over the period covering February-June 2008. Vertical profiles of absolute humidity and integrated water vapor (IWV) as measured by HAMSTRAD were compared with measurements from radiosondes launched in three different sites: Lannemezan (43?07'N, 0?23'E, 610 m asml), France (~30 km northeast from PdM), Bordeaux-Me?rignac Airport (44?49'N, 0?42'W, 50 m asml), France ( ~ 220 km northwest from PdM), and Zaragoza (41?39'N, 0?53'W, 263 m asml), Spain ( ~170 km southwest from PdM). The validation process also used the vertical profiles of tropospheric H2O as measured by the nadir-viewing infrared atmospheric sounding interferometer (IASI) instrument aboard the MetOp-A space platform. The temporal evolution of the HAMSTRAD H2O measurements above the PdM station is very consistent with IASI, sonde, and in situ measurements, tracking the same atmosphere from a dry period in February to a wet period in June. HAMSTRAD showed unrealistic values in periods of well-established snow tempest. While the sensitivity of the HAMSTRAD measurements tends to be degraded 6 km above the altitude of the instrument, namely, above 8877 m asml, the HAMSTRAD measurements seem reasonable at the uppermost retrieval level (namely, 10 km, 12 877 m asml). In May, the wet periods are systematically showing a good agreement between sonde and HAMSTRAD IWV fields and H2O below 6777 m asml but a dry bias of IASI by more than 4-kg m-2 IWV, where- – as outside of these periods, the three data sets behave consistently. Since the best results (mean, standard deviation, bias, and correlation) are obtained when the HAMSTRAD radiometer operates in the very dry conditions of February, namely, in dryness conditions comparable to Dome C summertime values, we are very confident in the optimal use of the instrument when deployed in Antarctica. |

| Abstract |
This Paper Assesses The Quality Of Iasi (Infrared Atmospheric Sounding Interferometer)/metop-a (Iasi-a) And Iasi/metop-b (Iasi-b) Ozone (O3) Products (Total And Partial O3 Columns) Retrieved With The Fast Optimal Retrievals On Layers For Iasi Ozone (Forli-o3; V20151001) Software For 9 Years (2008ājuly 2017) Through An Extensive Intercomparison And Validation Exercise Using Independent Observations (Satellite, Ground-based And Ozonesonde). Compared With The Previous Version Of Forli-o3 (V20140922), Several Improvements Have Been Introduced In Forli-o3 V20151001, Including Absorbance Look-up Tables Recalculated To Cover A Larger Spectral Range, With Additional Numerical Corrections. This Leads To A Change Of ā¼4% In The Total Ozone Column (Toc) Product, Which Is Mainly Associated With A Decrease In The Retrieved O3 Concentration In The Middle Stratosphere (Above 30hpa/25km). Iasi-a And Iasi-b Tocs Are Consistent, With A Global Mean Difference Of Less Than 0.3% For Both Daytime And Nighttime Measurements; Iasi-a Is Slightly Higher Than Iasi-b. A Global Difference Of Less Than 2.4% Is Found For The Tropospheric (Tropo) O3 Column Product (Iasi-a Is Lower Than Iasi-b), Which Is Partly Due To A Temporary Issue Related To The Iasi-a Viewing Angle In 2015. Our Validation Shows That Iasi-a And Iasi-b Tocs Are Consistent With Gome-2 (Global Ozone Monitoring Experiment-2), Dobson, Brewer, Saoz (SystĆØme D'analyse Par Observation ZĆ©nithale) And Ftir (Fourier Transform Infrared) Tocs, With Global Mean Differences In The Range Of 0.1%ā2% Depending On The Instruments Compared. The Worst Agreement With Uvāvis Retrieved Toc (Satellite And Ground) Is Found At The Southern High Latitudes. The Iasi-a And Ground-based Toc Comparison For The Period From 2008 To July 2017 Shows The Long-term Stability Of Iasi-a, With Insignificant Or Small Negative Drifts Of 1%ā3%decadeā1. The Comparison Results Of Iasi-a And Iasi-b Against Smoothed Ftir And Ozonesonde Partial O3 Columns Vary With Altitude And Latitude, With The Maximum Standard Deviation Being Seen For The 300ā150hpa Column (20%ā40%) Due To Strong Ozone Variability And Large Total Retrievals Errors. Compared With Ozonesonde Data, The Iasi-a And Iasi-b O3 Tropo Column (Defined As The Column Between The Surface And 300hpa) Is Positively Biased In The High Latitudes (4%ā5%) And Negatively Biased In The Midlatitudes And Tropics (11%ā13% And 16%ā19%, Respectively). The Iasi-a-to-ozonesonde Tropo Comparison For The Period From 2008 To 2016 Shows A Significant Negative Drift In The Northern Hemisphere Of -8.6Ā±3.4%decadeā1, Which Is Also Found In The Iasi-a-to-ftir Tropo Comparison. When Considering The Period From 2011 To 2016, The Drift Value For The Tropo Column Decreases And Becomes Statistically Insignificant. The Observed Negative Drifts Of The Iasi-a Tropo O3 Product (8%ā16%decadeā1) Over The 2008ā2017 Period Might Be Taken Into Consideration When Deriving Trends From This Product And This Time Period. |
